Chemical stability
no data available
Possibility of hazardous reactions
Decomposes on heating and on contact with acids. Decomposes under the influence of light. This produces toxic and corrosive gases including chlorine (see ICSC 0126). The substance is a strong oxidant. It reacts violently with combustible and reducing materials. This generates fire and explosion hazard. The solution in water is a strong base. It reacts violently with acid and is corrosive. Attacks copper and its compounds and light metals.

Other Information
Household bleaches usually contain about 5% sodium hypochlorite (about pH11, irritant), and more concentrated bleaches contain 10-15% sodium hypochlorite (about pH13, corrosive).The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.Rinse contaminated clothing with plenty of water because of fire hazard.Also consult ICSC #0482 (Sodium hypochlorite, active chlorine <10%).
