3.1 Stability of bleach solutions

Even at room temperature, bleach solutions decompose more or less slowly, releasing oxygen and/or producing chlorate. It is important to remember that:

• the rate of decomposition increases with hypochlorite concentration and temperature;

• Decomposition is catalyzed by numerous metal salts such as Ni, Co, and Fe, present in trace amounts.

• The optimum concentration of free soda is around 10 g/L.

• Breakdown of bleach with release of oxygen

  The degradation of bleach with the release of oxygen follows the following reaction: $\text{NaClO}\to \text{NaCl}+\frac{1}{2}{\text{O}}_2$
