Name:citric acid
Citric acid is an important organic acid, also known as citricacid, colorless crystals, often with part of the crystal water,odorless, has a strong acidity, soluble in water. The calcium saltin cold water than hot water soluble, this property is often usedfor identification and separation of citric acid. Crystallizationcontrol suitable temperature can get anhydrous citric acid. In theindustry, food industry, cosmetic industry has many uses.
