tartrate Chem.|ˈtɑːtrət|
[a. F. tartrate, f. tartre, tartar n.1: see -ate1.]
A salt of tartaric acid (CO2H.(CHOH)2.CO2H) formed by substituting a metal or radical for the hydrogen of the carbonyl groups (CO2H).
These salts are very numerous, and are acid or neutral, according as one or both of the hydrogen atoms are replaced; thus, acid potassium tartrate is CO2H.(CHOH)2.CO2K; neutral potassium tartrate, CO2K.(CHOH)2.CO2K. The H atoms can also be replaced by two different metals or radicals, forming double salts, as sodium potassium tartrate, CO2.Na.(CHOH)2.CO2K, potassium antimonyl tartrate, CO2K.(CHOH)2.CO2SbO.
