Exp. 7.pdf - Experiment 7 Analysis of Commercial Chlorine ...- chlorine as a bleaching agent equation ,Experiment 7 Analysis of Commercial Chlorine Bleach Commercial bleaching agents contain the hypochlorite ion, ClO –, as the “active ingredient” for making clothes whiter or removing stains. This ion is generally in the form of the sodium salt, NaClO. Normally, when the strengths of various bleaches are compared, the standard oxidant for bleaching is assumed to be Cl 2.Sodium hypochlorite - WikipediaSodium hypochlorite (commonly known in a dilute solution as bleach) is a chemical compound with the formula NaOCl or NaClO, comprising a sodium cation (Na +) and a hypochlorite anion (OCl − or ClO −It may also be viewed as the sodium salt of hypochlorous acid.The anhydrous compound is unstable and may decompose explosively. It can be crystallized as a pentahydrate NaOCl ·5 H
