Tartaric Acid-Sugar Mixture

Tartaric Acid-Sugar Mixture

Tartaric acid occurs in one of three salt forms: Cream of tartar, tartar emetic, and Rochelle salt. Interestingly, the crystals of Rochelle salt have piezoelectric properties, and are employed as part of the conducting components in some microphones.

Sugars occur as several different molecular compounds, and they belong to a class of substances called carbohydrates. These typically sweet-tasting molecules are present in the sap of many seed plants, as well as in the milk of mammals.
