Q. Calcium sulphate, C a S O 4 is a white crystalline substance. Gypsum is a mineral or natural substance that is hydrate of calcium sulphate. 1.032 g sample of gypsum contains 0.816 g C a S O 4. How many moles of water are contained in gypsum per mole of C a S O 4. Give your answer in nearest integer. (C a = 40, S = 32)
Calcium salts may be incompatible with amines, amino acids, peptides, and proteins, which may form complexes. It is also anticipated that calcium sulfate would be incompatible with indomethacin, aspirin, aspartame, ampicillin, cephalexin, and erythromycin since these materials are incompatible with other calcium salts.
