Sodium percarbonate

Sodium percarbonate is a white crystalline water-soluble chemical compound of sodium carbonate and hydrogen peroxide. It is an oxidizing agent and ingredient in a number of home and laundry cleaning products. Despite the name it is in fact a carbonate perhydrate. Dissolved in water, it releases H2O2 and soda ash (sodium carbonate):


 * $$ [Na_2CO_3]_2 \cdot 3H_2O_2 \rightarrow 2Na_2CO_3 + 3H_2O_2 $$

Sodium percarbonate is the active ingredient in many powdered oxygen bleach products.
