It turns cloudy where CO2 is present. * Calcium arsenate (Ca3(AsO4)2) is used in insecticides. * Calcium carbide (CaC2) is used: to make acetylene gas (for use in acetylene torches for welding) and in the manufacturing of plastics. * Calcium chloride (CaCl2) is used: in ice removal and dust control on dirt roads, in conditioner for concrete, as an additive in canned tomatoes, and to provide body for automobile tires. * Calcium cyclamate (Ca(C6H11NHSO4)2) was used as a sweetening agent but is no longer permitted for use because of suspected cancer-causing properties. * Calcium gluconate (Ca(C6H11O7)2) is used as a food additive and in vitamin pills. * Calcium hypochlorite (Ca(OCl)2) is used: as a swimming pool disinfectant, as a bleaching agent, as an ingredient in deodorant, and in algaecide and fungicide. * Calcium permanganate (Ca(MnO4)2) is used in liquid rocket propellant, textile production, as a water sterilizing agent and in dental procedures. * Calcium phosphate (Ca3(PO4)2) is used as a supplement for animal feed, fertilizer, in commercial production for dough and yeast products, in the manufacture of glass, and in dental products. * Calcium phosphide (Ca3P2) is used in fireworks, rodenticide, torpedoes and flares. * Calcium stearate (Ca(C18H35O2)2 is used in the manufacture of wax crayons, cements, certain kinds of plastics and cosmetics, as a food additive, in the production of water resistant materials and in the production of paints. * Calcium sulfate (CaSO4·2H2O) is used as common blackboard chalk, as well as, in its hemihydrate form being more well known as Plaster of Paris. * Calcium tungstate (CaWO4) is used in luminous paints, fluorescent lights and in X-ray studies.
