Thermal Decomposition of Sodium Percarbonate

2Na2CO3·3H2O2 → 2Na2CO3 + 3H2O2

개요

Sodium percarbonate dissolves in water to release hydrogen peroxide and sodium carbonate. This controlled release of H2O2 makes it an effective solid oxygen bleach. It is marketed as an environmentally friendly alternative to chlorine bleach.
