Questions And AnswerBack Directory
[DESCRIPTION]

Colourless or translucent crystals, or a white crystalline powder; odourless

[FUNCTIONAL USES]

Synergist for antioxidants, acid, emulsifier, sequestrant, flavouring agent

[Solubility]

Freely soluble in water; sparingly soluble in ethanol

[Applications]

Tartaric acid and its derivatives have a plethora of uses in the field of pharmaceuticals. It has been used in the production of effervescent salts, in combination with citric acid, in order to improve the taste of oral medications. The potassium antimonyl derivative of the acid known as tartar emetic is included, in small doses, in cough syrup as an expectorant.

[Melting range]

200 - 206o with decomposition when heated rapidly in a sealed capillarytube

[substances]

N potassium permanganate while keeping the solution at 20o . The colour of the solution does not disappear within 3 min.

[METHOD OF ASSAY]

Weigh accurately about 2 g of the dried sample, dissolve it in 40 ml of water, add phenolphthalein TS, and titrate with 1 N sodium hydroxide. Each ml of 1 N sodium hydroxide is equivalent to 75.04 mg of C4H6O6.
