(-)-(2S,3S)-Tartaric Acid, C4H6O6
molar mass: 150.1 g/mol.
a rare form of this acid with no optical rotation was called Racemic Acid (from "+ "racemus=bunch of grapes, L). Experiment showed that this was a 50-50 mixture of the (+) and (-) forms of tartaric acid (which were separated by hand-picking crystals of the sodium ammonium salt of racemic acid) and this has led all such 50-50 mixtures of the two enantiomers being labelled racemic
