| Physical and Chemical Properties | Colorless crystals or white crystalline powder, odorless, sour taste. It is a mixture of equal amounts of dextrorotatory and levorotatory tartaric acid, often containing one or two crystals of water, which is lost when heated to 100°C. Stable in air, density 1.697. its solubility in water 20.6(20°C), ether solubility of about 1%, ethanol solubility of 5.01(25°C). |
| Use | Widely used in food, medicine, chemical, light industry and other industries. For example, as a beer foaming agent, food acidulant, flavoring agent, used for cool drinks, candy, fruit juice, sauce, cold dishes, baking powder, etc., its sour taste is 1.3 times that of citric acid, especially suitable for the acidulant of grape juice. In tanning, photography, glass, enamel, telecommunications equipment and other industries also have a very important role. |
