Everything You Need to Know About Bleach

Bleach is the common name for a solution of 2.5%  sodium hypochlorite in water. Its also called chlorine bleach or liquid bleach. Another type of bleach is oxygen-based or peroxide bleach. While you may know bleach is used to disinfect and remove stains, there is more to know about this everyday chemical to use it safely and effectively. Here are some important facts about this solution. Useful Bleach Facts Bleach has a shelf life and expiration date. On average, a container of unopened bleach loses 20% of its effectiveness each year. Once opened, bleach starts to lose a significant amount of its power after 6 months.Chlorine bleach is more effective as a disinfectant when its diluted rather than if its used at full strength. A typically recommended dilution is 1 part bleach to 9 parts water.A higher percentage of bleach is needed if a large quantity of organic material (e.g., blood, protein) is present, as these materials react with bleach and tend to neutralize it.If you add sodium hypochlorite bleach to whiten laundry or remove stains, its better to add it after the wash cycle has already filled with water and started agitation. If you add bleach together with detergent, you risk diminishing the effectiveness of enzyme-based stain removers and the detergent. On the other hand, oxygen-based bleach is best added to warm or hot water before clothes are added. Oxygen-based bleaches are g enerally color-safe and will preserve whiteness, but will not remove color. Sodium hypochlorite bleach does whiten fabrics ​but is not safe for all materials.Bleach reacts with several other chemicals to release toxic vapors. Its generally inadvisable to mix bleach with other cleaners. In particular, avoid mixing bleach with acetone, alcohol, vinegar  or other acids, or ammonia.Bleach can corrode metal, so if you clean or disinfect a metal surface with bleach, its important to wipe it down with water or alcohol afterward.Although its commonly believed drinking bleach can lead to a negative blood or urine test for drug use, this is untrue.While chlorine bleach is a powerful disinfectant, peroxide bleach is not suitable for this purpose. Chlorine bleach disinfects because it is an oxidizer, capable of disrupting microbial cells. Oxidation is also how chlorine bleach removes color. Sodium hypochlorite breaks bonds in the chromophore or colored portion of a molecule, rendering it colorless. Reducing bleaches also exist, which also change chemical bonds and alter how a molecule absorbs light.Chlorine bleach was first used to disinfect water in 1895 for  New York Citys Croton Reservoir.Household bleach may be made using water, caustic soda, and chlorine. The process of electrolysis is used to produce chlorine and caustic soda by running an electric current through a solution of table salt (sodium chloride) in water. Caustic soda and chlorine react to form sodium hypochlorite. All that is needed is to bubble chlorine gas through caustic soda solution. Since chlorine gas is toxic, bleach is not a chemical one should make at home.Although the odor of chlorine is apparent in bleach, when bleach is used, the chemical reaction tends to produce salt water and not chlorine gas.Although the toxic chemical dioxin has been known to occur in bleaching products using in the wood pulp and paper industry, household bleach is free from dioxin because gaseous chlorine mus t be present for dioxin to form.

Commencement of Revolution Historians have stated that the American colonist â€Å"were never so British† after the French and Indian War in 1763, but in 1775 the first shots of the American Revolution were fired.

Examining The Examples Of A Tragic Hero English Literature Essay Free Essays

A premier illustration of a tragic hero is John Proctor, from Arthur Millers, The Crucible.A Proctor is easy placed in this class of heroes because he has features that define who may be considered such a hero, such as the fact that he is extremely regarded in the community, that he has a tragic defect, that he dies and embraces decease with self-respect and that he is portrayed as a human being like his readers to which causes a katharsis of emotions in them. Leon Golden writes that â€Å" the ideal Aristotelean form of tragedyaˆÂ ¦ the autumn from felicity to wretchedness, caused by a serious rational mistake, on the portion of a hero who is worthy of regard†¦ † ( Golden ) . We will write a custom essay sample on Examining The Examples Of A Tragic Hero English Literature Essay or any similar topic only for you Order Now John makes such â€Å" mistakes † due to his tragic defects, which result in his ruin, but in malice of these defects in his character, he is extremely regarded within his community. He makes a serious mistake in judgement, realizes that he has made an irreversible error, and while he recognizes that he must be put to decease, maintains his self-respect and trades with his destiny with a step of credence, like a tragic hero is supposed to make. Finally, John has the intrinsic ability to pull out sympathy and commiseration from his readers which is besides a celebrated quality of the authoritative tragic hero. John Proctor is hence the quintessential illustration of a tragic hero.A It is apparent early on thatA John ProctorA wasA extremely esteemed within the community, A because heA wasA called toA Reverend Parris ‘ family toA see howA the Reverend ‘s ailment daughterA was making. The rigorous Puritan members of Salem besides commended him for hanging the door of the church.A Despite the strength in which the Puritans regarded their faith and the contempt they shared for those less â€Å" spiritual † than they were, Arthur Miller writes that â€Å" Proctor, respected and even feared in SalemaˆÂ ¦ † ( Miller 20 ) . John ProctorA wasA still considered to be an honest, hardworkingA adult male and aA God-fearingA Christian, even though he did n’t go to church and was non, in any manner, perfect. James Martine suggests that â€Å" the ideal supporter of calamity, so, says Aristotle, must be a adult male like ourselves, one who does non possess righteousness and virtuousness to flawlessness, but whose character is held in high-esteem by all † ( Martine ) . Therefore, Proctor fits the portion of Aristotle ‘s tragic hero definition which claims he must be a well-respected individual within the narrative ‘s chief community ( even if he is non near to being Godhead ) . However, as is the instance for every tragic hero, a tragic defect that John Proctor possesses finally led to his tragic terminal. One of John Proctor ‘s tragic defects was his unfaithfulness. Like Larry Brown believes, â€Å" Miller created the matter between Proctor and Abigail as a cardinal motivational factor in Proctor ‘s character † ( Brown ) . Because of the matter he pursues with 17 twelvemonth old, Abigail, the remainder of the events that lead to his day of reckoning unfold. Abigail ‘s green-eyed monster of Proctor ‘s married woman, Elizabeth, cause her to get down a commotion in Salem and to impeach people of take parting in witchery because she believes if she removes Elizabeth, by impeaching her of being a enchantress she could hold the desirable John Proctor all to herself.A Another defect of Proctor that consequences in his decease is his pride. Martine agrees that for a hero to be considered tragic, â€Å" the hero must be a extremely moral person who has a tragic defect, a tragic flaw. This defect is frequently hubris-commonly characterized as prideaˆÂ ¦ † ( Martine ) . Proctor is delayed in the confession of his wickedness because it is of extreme importance to him to keep a good name. Had he owned up to the matter earlier on in the procedure, he could hold shown the tribunal that Abigail had a sensible alibi and the whole events of the Salem enchantress tests could hold been stopped before they even began. Because of John Proctor ‘s serious defect in character and his awful wickedness, he is hanged upon the gallows of Salem for all to see. Not many people accept decease with such awards and unity as Proctor does. A Out of self-respect and pride in his household and himself, John Proctor decides to be hanged instead than lie and falsely confess to hold practiced witchery and everlastingly be associated with it. Proctor, in mention to the prevarication that subscribing his confession would be, says â€Å" Because I can non hold ano ther in my life! Because I lie and sign myself to prevarications † ( Miller Act IV ) . In add-on, he does non desire to subject to the giving over of names of other people in the community, feigning that they were enchantresss, to acquire himself off the hook, or in this instance, gallows. â€Å" The tragic terminal of the drama comes at the really point where Proctor found his morality and award that he thought he lost † ( University of Houston- Clear Lake ) . The pride that led to Proctor ‘s ruin is the same pride that causes him to decease in self-respect, without subscribing to prevarications. John Proctor hides his criminal conversation with Abigail from the tribunal for the interest of repute, until he must squeal: â€Å" I have made a bell of my award! I have rung the day of reckoning of my good name. † However, as he is pressured to curse falsely that he dealt in witchery, Proctor realizes it is his name in the sense of personal unity, being true to himself, non his repute among others that affairs most of all ( Brown ) . The concluding facet of a tragic hero that John Proctor undoubtedly encompasses is his relatability, which causes the other characters in the drama and its readers to sympathize with him. Proctor is displayed as a mere human being with defects and battles which in many ways mirror our ain defects and battles. â€Å" This deep-rooted temperament of ‘frailty ‘ is Proctor ‘s ain indispensable humanity and demonstrates him to be ‘a adult male merely like ourselves. ‘ And since this is so, the attendant katharsis arouses, and purgings, our ain commiseration and fright † ( Martine ) . Some of his greatest battles are happening himself and covering with the guilt he feels for holding an matter, which he finally comes to accept as Martine says ; â€Å" John Proctor is heroic because he accepts his guilt and indicts the society that would coerce him to give over his scruples. To make both, he must be self-discovered, self-recognized and eventually self-ac cepting † ( Martine ) . Proctor is at his tallness of ego consciousness when he realizes how of import it is to keep his unity. Robert Heilman explains that Shakespeare made the tragic hero, â€Å" a figure capable of self-awareness and self-judgment † ( Heilman ) . Just as Miller gave John Proctor the ability to hold self-awareness, William Shakespeare gave his tragic heroes the same ability. Because the readers find themselves similar to Invigilate in that they besides are flawed, they are able to to the full sympathize with him and throw themselves into the emotional convulsion of the narrative. Therefore, when the narrative of John Proctor is read, the reader experiences a katharsis of emotions. They feel fear for him, throughout the tests and when his destiny is being determined. They feel sympathy for him as he approaches his decease, right after he and Elizabeth eventually mend their matrimony. A narrative of a tragic hero tends to accomplish that consequence on its readers. How to cite Examining The Examples Of A Tragic Hero English Literature Essay, Essay examples

Salome Monologue Essay Paper Example For Students

Salome Monologue Essay Paper A monologue from the play by Oscar Wilde NOTE: This monologue is reprinted from Representative One-Act Plays by British and Irish Authors. Ed. Barrett H. Clark. Boston: Little, Brown, and Co., 1921. SALOME: Ah! thou wouldst not suffer me to kiss thy mouth, Iokanaan. Well! I will kiss it now. I will bite it with my teeth as one bites a ripe fruit. Yes, I will kiss thy mouth, Iokanaan. I said it; did I not say it? I said it. Ah! I will kiss it now. But wherefore dost thou not look at me, Iokanaan? Thine eyes that were so terrible, so full of rage and scorn, are shut now. Wherefore are they shut? Open thine eyes! Lift up thine eyelids, Iokanaan! Wherefore dost thou not look at me? Art thou afraid of me, Iokanaan, that thou wilt not look at me? And thy tongue, that was like a red snake darting poison, it moves no more, it speaks no words, Iokanaan, that scarlet viper that spat its venom upon me. It is strange, is it not? How is it that the red viper stirs no longer? Thou wouldst have none of me, Iokanaan. Thou rejectedest me. Thou didst speak evil words against me. Thou didst bear thyself toward me as to a harlot, as to a woman that is a wanton, to me, Salome, daughter of Herodias, Princess of Judaea! Well, I still live, but thou art dead, and thy head belongs to me. I can do with it what I will. I can throw it to the dogs and to the birds of the air. That which the dogs leave, the birds of the air shall devour. Ah, Iokanaan, Iokanaan, thou wert the man that I loved alone among men! All other men were hateful to me. But thou wert beautiful! Thy body was a column of ivory set upon feet of silver. It was a garden full of doves and lilies of silver. It was a tower of silver decked with shields of ivory. There was nothing in the world so white as thy body. There was nothing in the world so black as thy hair. In the whole world there was nothing so red as thy mouth. Thy voice was a censer that scattered strange perfumes, and when I looked on thee I heard strange music. Ah! wherefore didst thou not look at me, Iokanaan? With the cloak of thine hands, and with the cloak of thy blasphemies thou didst hide thy face. Thou didst put upon thine eyes the covering of him w ho would see God. Well, thou hast seen thy God, Iokanaan, but me, me, thou didst never see me. If thou hadst seen me thou hadst loved me. I saw thee, and I loved thee. Oh, how I loved thee! I love thee yet, Iokanaan. I love only thee. I am athirst for thy beauty; I am hungry for thy body; and neither wine nor apples can appease my desire. What shall I do now, Iokanaan? Neither the floods nor the great waters can quench my passion. I was a princess, and thou didst scorn me. I was a virgin, and thou didst take my virginity from me. I was chaste, and thou didst fill my veins with fire. Ah! ah! wherefore didst thou not look at me? Ah! I have kissed thy mouth, Iokanaan, I have kissed thy mouth. There was a bitter taste on thy lips. Was it the taste of blood? Nay; but perchance it was the taste of love. They say that love hath a bitter taste. But what matter? what matter? I have kissed thy mouth.
