R,S-tartaric acid is a meso form. Meso-tartaric acid is a 2,3-dihydroxybutanedioic acid that has meso configuration. This is also known as internal compensation. the effect of one-half of the molecule is neutralized by other. Hence, meso form is said to be a diasteromer. Meso compound is optically inactive due to internal compensation. In general, any compound like this, having stereogenic carbons but also a plane of symmetry, is called a meso compound.
