The chemical formula of DL-Tartaric acid shown above is based on the molecular formula indicating the numbers of each type of atom in a molecule without structural information, which is different from the empirical formula which provides the numerical proportions of atoms of each type.
The above chemical formula is the basis of stoichiometry in chemical equations, i.e., the calculation of relative quantities of reactants and products in chemical reactions.
The law of conservation of mass dictates that the quantity of each element given in the chemical formula does not change in a chemical reaction.
Thus, each side of the chemical equation must represent the same quantity of any particular element based on the chemical formula.

TARTARIC ACID:
Tartaric acid has two asymmetrical carbon atoms and three chiral isomers; the dextro-, levo-, (optically active) and meso- forms (optically inactive).
The D- and L-tartaric acids are said to be enantiomorphs (each molecule is asymmetrical and has the mirror image of the other).
There are two asymmetrical carbon atoms in meso-tartaric acid, but the molecule is symmetrical and does not exhibit optical activity; the optical activity is internally compensated, the effect of one asymmetrical carbon atom balancing the effect of the other.
A pair of optical isomers such as d-tartaric acid and mesotartaric acid, which are not enantiomorphs, are called diastereoisomers.
Tartaric Acid is a useful raw material for the synthesis of other chiral compounds.
L-tartaric acid (called also D-2,3-dihydroxysuccinic acid or L-2,3-dihydroxybutanedioic acid) is chiefly found in many plants, especially grapes.
L-tartaric acid can be partially converted to the others by heating L-tartaric acid with an aqueous alkali (potassium hydroxide) as the isomeric forms differ from each other in boiling points.
L-tartaric acid can be synthesized by the reaction of maleic acids or fumaric acids with aqueous potassium permanganate.
Tartaric acid is biodegradable and no pollution problems are known.
Tartaric acid is used chiefly in the form of Tartaric acid's salts, e.g., cream of tartar (potassium hydrogen tartrate), Rochelle salt (potassium sodium tartrate) and Tartar Emetic (antimony potassium tartrate).
Tartaric acid is used to enhance flavours in foods, confectionery and beverages.
