why bleach deteriorate?
« 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?

You need to show work.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

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 ??
