Sodium carbonate (also known as washing soda or soda ash), Na2CO3, is a sodium salt of carbonic acid and is a fairly strong, non-volatile base. It most commonly occurs as a crystaline heptahydrate which readily effloresces to form a white powder, the monohydrate. It has a cooling alkaline taste, and can be extracted from the ashes of many plants. It is produced artificially in large quantities from common salt.
