Sodium carbonate (Na 2 CO 3, also called soda ash) is one of the largest volume mineral products in the inorganic chemicals industry. Sodium carbonate commonly occurs as a crystalline decahydrate (Na 2 CO 3 ·10H 2 O), which readily effloresces to form a white powder, the monohydrate (Na 2 CO 3 ·H 2 O).
