Tartaric Acid and Tartrates

Tartaric acid is a white crystalline diprotic organic acid. It occurs naturally in many plants, particularly grapes, bananas, and tamarinds, and is one of the main acids found in wine. It is added to other foods to give a sour taste, and is used as an antioxidant. Salts of this material are known as tartrates. It is a dihydroxy derivative of succinic acid.
