Q: What is sodium percarbonate?

A: Sodium percarbonate (or sodium carbonate peroxyhydrate) is an addition compound of sodium carbonate and hydrogen peroxide. When dissolved into water, its releases H₂O₂ and soda ash (sodium carbonate).

The type of reaction shown as follows： 2Na₂CO3.3H₂O₂ → 2Na₂CO3+ 3H₂O₂ 

The pH of the resulting solution is typically alkaline, which activates the H₂O₂ for bleaching. The dry powder contains about 30% w/w H₂O₂.
