Redox Titration Analysis of a Commercial Bleach Purpose To perform a redox titration. To determine the amount of hypochlorite ion present in commercial bleach. Introduction Many commercial products‚ such as bleaches and hair coloring agents‚ contain oxidizing agents. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (sometimes written NaOCl). Commercial bleaches are made by bubbling chlorine gas into a sodium hydroxide solution. Some of the chlorine is oxidized to

Why do they do so? The reason of getting yellow. The solution to the problem. Difference between sulfide bleach and chlorine bleach. PPT 3 We heard words such as “bleach for unbleachables” from TV commercials. But what exactly is bleaching? Does it mean making things turn into a lighter

Analysis of Commercial Bleach AP Chemistry Introduction: Many commercial products are effective because they contain oxidizing agents. Some products that contain oxidizing agents are bleaches‚ hair coloring agents‚ scouring powders‚ and toilet bowl cleaners. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (sometimes written NaOCl). Commercial bleaches are created by bubbling chlorine gas into a sodium hydroxide solution (remember this from your “funky redox rxns”?)

Analysis of a Commercial Bleach Purpose: The purpose of this lab is to determine the amount of sodium hypochlorite (NaClO) in commercial bleach. This can be done by forming triiodide ions. To make the measurement more accurate‚ starch was added to help determine the endpoint of the solution. The significance of this lab is that industry can use these techniques to determine the amount of NaClO in the bleach of the rival industry and improve it. Hypothesis: The hypothesis is that‚ an accurate

Analysis of Commercial Bleach Lab I. Purpose In this experiment‚ the amount of sodium hypochlorite in a commercial bleach will be determined by reacting it with sodium thiosulfate in the presence of iodide ions and starch. A solution of sodium thiosulfate of known concentration will be added to the bleach using a buret in a titration procedure. The disappearance of the dark blue color of the starch-iodine complex will signal the end point. II. Procedures Pre-Lab Questions 1. What is

Bleach (ブリーチ Burīchi?) is a Japanese manga series written and illustrated by Tite Kubo. Bleach follows the adventures of Ichigo Kurosaki after he obtains the powers of a Soul Reaper (死神 Shinigami?‚ literally‚ "Death God") —a death personification similar to the Grim Reaper—from another Soul Reaper‚ Rukia Kuchiki. His newfound powers force him to take on the duties of defending humans from evil spirits and guiding departed souls to the afterlife. Bleach has been serialized in the Japanese manga anthology Weekly

Element: Chlorine General Information We researched the chemical element known as chlorine. Chlorine has an atomic number of 17 and an atomic weight of 35.453. It has a valence number of 3. The element has 3 energy levels. Chlorine exists as a greenish-yellow gas at normal temperatures and pressures. Chlorine is second in reactivity only to fluorine among the halogen elements. Chlorine is a nonmetal. It is estimated that 0.045% of the earth’s crust and 1.9% of sea water are chlorine. Chlorine

Chlorine Zachary Grindle Chemistry 1301 Professor Bott June 24‚ 2010 Chlorine has an atomic mass of 35.453‚ atomic number 17‚ is a member of the halogen family (VIIA)‚ and its symbol is “Cl”. Chlorine contains 17 protons and 18 neutrons in is nucleus. There are two isotopes for chlorine as well; Cl-35 and Cl-37. Chlorine was discovered in 1774 by Swedish chemist Carl Wilhelm Sheele. Sheele came upon chlorine when he put a few drops of hydrochloric acid (HCl)‚ then known as muriatic acid
