Module: 3 Lecture: 9 NPTEL

Module: 3 Lecture: 9 SODIUM CARBONATE INTRODUCTION Sodium carbonate (Na 2 CO 3) also known as washing soda or soda ash, is a sodium salt of carbonic acid. Most commonly occurs as a crystalline heptahydrate, which readily effloresces to form a white powder, the monohydrate. Sodium carbonate is domestically well known as a water softener.
