Tartaric acid is a dihydroxy and dicarboxylic acid as it has two OH and two COOH groups. Tartaric acid is found in many plants, e.g., grapes; this natural acid is chiefly the dextrorotatory d-tartaric acid, called also d-2,3-dihydroxysuccinic acid or l-2,3-dihydroxybutanedioic acid. (ii) Each of two carbon atoms of double bond must have different substituents, which may be same or different.Meso-tartaric acid optically inactive. Number of possible optical isomers in compounds containing different no. Main Difference – Racemic Mixture vs Meso Compound. The meso compound is bisected by an internal plane of symmetry that is not present for the non-meso isomers (indicated by an X). 1 and 2 are clearly enantiomers, however, what may not be immediately apparent is that 3 and 4 are in fact the same molecule. Its salt, potassium bitartrate, commonly known as cream of tartar, develops naturally in the process of fermentation.It is commonly mixed with sodium bicarbonate and is sold as baking powder used as a leavening agent in food preparation. It is optically inactive due to internal compensation. It can not be separated into two forms. Meso compound is optically inactive due to internal compensation. of meso l- forms m = 0. It is used as an antioxidant. This molecule does have a plane of symmetry, and is therefore achiral. A meso compound is one which is optically inactive although have more than one chiral carbons. One of the isomers of tartaric acid is a meso compound: If you rotate the molecule 180° you will have the same apparent stereochemistry.

Salts of tartaric acid are known as tartarates. Pasteur studied tartaric acids (wine fermentation) and discovered the two chiral forms, the levorotatory form and the dextrorotatory form; he thus explains – which has not been included – the optical neutrality of mixing two components. It exists as a pair of enantiomers and an achiral meso compound.
