Randi Sodium and potassium tartrate

Randi Sodium and potassium tartrate contains not less than 98.0 per cent and not more than the equivalent of 101.0 per cent of the anhydrous substance. Rochelle Salt presents itself as white or almost white crystalline powder or colorless transparent crystals. Tetrahydrate salt crystals are translucent. At 100°C, salt loses three molecules of water; at 130-140°C it becomes anhydrous; at 220°C it starts to decompose. Rochelle Salt is very soluble in water and practically insoluble in alcohol. In particular, salt melts in 0.9 parts of water, resulting in an aqueous solution, weakly alkaline. Its use is mainly technical, but it is also employed in food and pharmaceutical industries.
