Physical and chemical properties:
Colorless crystalline or white crystalline powder, odorless, acidity. It is a mixture of equal amount of dextral and levotartaric acid, often containing one or two crystalline water, and the water is lost when heat is 100 C. In the air, the density is 1.697, the solubility of the water is 20.6 (20 C), the solubility in ether is about 1%, the solubility of the ethanol is 5.01 (25 C).
It is widely used in food, medicine, chemical industry, light industry and other industries. Such as beer foaming agent, sour agent, food flavoring agent, used in soft drinks, candy, fruit juice, sauce, cold dish, baking powder, its acidity is 1.3 times of citric acid, especially suitable for the Grape Juice sour agent. In photography, leather, glass, enamel, telecommunications equipment and other industries also have a very important role.
