Description

Colorless, transparent crystals that occur naturally in wine lees. Tartaric acid is used in baking powders (potassium hydrogen tartrate), leather tanning and effervescent beverages. Tartaric acid acts as a buffering agent and Sequestrant. It is used by dyers to print a blue ferric tartrate color and to remove some mordants from solution. Tartaric acid (and tartrates) reacts with ammonio-silver nitrate to produce metallic Silver; this reaction is used in photographic developing solutions and for silvering mirrors.

Synonyms and Related Terms

tartar; dihydroxysuccinic acid; L-tartaric acid; racemic acid; uvic acid; Weinsäure (Deut.); Ácido tartárico (Esp., Port.); Wijnsteenzuur (Ned.)
