Best Answer. Copy. No it is not a salt. Gypsum is a mineral that occurs in nature as flattened and often twinned crystals and transparent cleavable masses called selenite. Wiki User. ∙ 13y ago.Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates. In the form of γ- anhydrite (the anhydrous form), it is used as a desiccant. One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum.

Gypsum is a non-metallic mineral, found in rock form. It is composed of 79.1% calcium sulphate and 20.9% water, by weight. Chemists call it Hydrous Calcium Sulphate, and as there is one molecule of calcium sulphate combined with two molecules of water. It has the chemical formula CaSO 4 2H 2 0. By volume this works out to nearly 50% water in ... Gypsum is often formed from evaporating water and usually contains water molecules in its crystalline structure. The ᐧ2H 2 O in the formula indicates the water molecules are whole H 2 O. This is different from minerals like amphibole, which contain a hydroxide ion (OH – ) that is derived from water, but is missing a hydrogen ion (H + ).
Thick gypsum beds such as are found in Kansas present further problems. For example, deposition of a 30-foot bed of gypsum in the Blaine formation would require the evaporation of more than 8 miles of sea water, assuming that sea water contained the same amount of calcium sulfate in Blaine time as it does now.rock salt. shale. sandstone. basalt. rock salt.
