CAS number: 87-69-4
Tartaric acid and its salts are soluble in water, with some differences
among individual substances. calcium tartrate and potasim hydrogen
tartrare te less soluble than tartaric acid and the other salts.
The determination of this property was done according to a weight of
evidence approach based on available literature reference and QSAR
calculation. 1390 mg/L (20 °C)
A collection of the water solubility data was performed for tartaric
acid and its salts (i.e. monosodium, monopotassium, sodium potassium,
sodium, potassium and calcium tartrate). A summary of these data (with
the indication of the minimum-maximum value of water solubility) is
water solubility (g/L)
interpretation of result
potassium hydrogen tartrate
potassium sodium tartrate
sodium hydrogen tartrate
The water solubility of dextrotartaric ((+)-tartaric acid), levotartaric
((-)-tartaric acid) and mesotartaric acid are of the same order of
magnitude. Only the solubility of the racemic form of acid tartaric
((±)-tartaric acid) is lower than the other forms of tartaric acid.
Overall, all forms of tartaric acid are judged as very soluble in water.
With regard to acid tartaric salts, although there are significant
differences in the found values, all substances resulted to be water
