Chemical Properties: DL-Tartaric acid is a water- and alcohol-soluble colorless crystalline solid with a characteristic acid taste and a melting temperature of 170°C(338°F). Naturally occurring tartaric acid is generally of the L-configuration (based on the absolute configuration of D-glyceric acid). The L-forms of tartrates are dextrorotatory in solution and thus are designated as L(+)-tartrates. It is also known as dihydroxy succinic acid. Tartaric acid is used as a chemical intermediate and a sequestrant,as well as in tanning, effervescent beverages, baking powder, ceramics, photography, textile processing,mirror silvering,and metal coloring.
