sulfuric acid, calcium salt (1:1)
a calcium salt that is used for a variety of purposes including: building materials, as a desiccant, in dentistry as an impression material, cast, or die, and in medicine for immobilizing casts and as a tablet excipient. it exists in various forms and states of hydration. plaster of paris is a mixture of powdered and heat-treated gypsum. Used in foods as an anticaking agent, colouring adjunct, dough strengthener, drying agent, firming agent, formulation aid, leavening agent, nutrient supplement, pH control agent, processing aid, stabiliser, thickener, synergist and texturiser; also used as an additive in the bleaching of flour by benzoyl peroxide Calcium sulfate is a common component of fouling deposits in industrial heat exchangers. It is because its solubility decreases with increasing temperature in hot water (see the figure).; Calcium sulfate is a common laboratory and industrial chemical. In the form of ?-anhydrite (the nearly anhydrous form), it is used as a desiccant. It is also used as a coagulant in products like tofu. In the natural state, unrefined calcium sulfate is a translucent, crystalline white rock. When sold as a color-indicating variant under the name Drierite, it appears blue or pink due to impregnation with cobalt chloride, which functions as a moisture indicator. The hemihydrate (CaSO4.~0.5H2O) is better known as plaster of Paris, while the dihydrate (CaSO4.2H2O) occurs naturally as gypsum. The anhydrous form occurs naturally as ?-anhydrite. Depending on the method of calcination of calcium sulfate dihydrate, specific hemihydrates are sometimes distinguished: alpha-hemihydrate and beta-hemihydrate. They appear to differ only in crystal size. Alpha-hemihydrate crystals are more prismatic than beta-hemihydrate crystals and, when mixed with water, form a much stronger and harder superstructure.
