Appearance: There are three stereoisomers of tartaric acid: right-handed tartaric acid, left-handed tartaric acid and meso-racemic tartaric acid. A mixture of equal amounts of right-handed and left-handed groups whose optical activity cancels each other out is called racemic tartaric acid. Mesomers do not occur in nature and can be chemically synthesized. All tartaric acids are colorless crystals that dissolve easily in water. Melting point 166-170℃
