Title: why bleach deteriorate?
Post by: jackson on September 30, 2006, 10:07:40 PM
Bleaches may deteriorate due to two main reasons.One is the reaction with carbon dioxide in air.
Cl-(aq)+ClO-(aq)+CO2(g)?Cl2(aq)+CO3 2-(aq)
What is the other main reason?

In the experiment,sodium chlorate(I) in commercial bleach is allowed to react with excess potassium iodide(KI) and sulphuric acid(H2SO4) to produce iodine(I2).
The iodine formed is then titrated against standard sodium thiosulphate solution (Na2S2O3).

then,what is the other reason ??
