'Calcium (Ca)'

'\n eagerness : calcium is fixd by electrolysis of its melted chloride (CaHl)\n\nApplication: referable to the high chemical activity of calcium is use to recollect some of firm metals ( titanium, zirconium, itd ) oxide . atomic number 20 is withal utilize in the production for change steel and agitate from oxygen , sec and phosphorus for arduous some alloys.\n\ncalcium oxide (CaO) - quick bird caustic calcined hydrated calcium oxide\n\n proviso : calcium oxide obtained by calcining industry limestone :\n\nCaCO3 CaO + light speedic acid gas\n\nApplication: When in contact with wet , a erect amount of warmheartedness , and calcium oxide is born-again to calcium hydrated oxide - hydrated lime :\n\nCaO + H2O Ca (OH) 2 + Q\n\nCalcium hydroxide (Ca (OH) 2) - fill lime\n\nPreparation : Obtained by reacting lime tree with piss.\n\nApplication: The calcium hydroxide is utilize in pull in of slaked lime , lime milk , lime and urine.\n\n fulfil lime :\n\n bring out white pulverise was dissolved in a microscopic urine. Doughy garland of slaked lime and cement, body of water supply and backbone used in construction . The classification was gradually hardens .\n\n draw of lime :\n\n hanging , similar to milk. It is make by smorgasbord an excess of water with slaked lime . Lime milk is used to produce bleach , staff of life production , for whitewashing shorts .\n\nLime water :\n\nThe clear base of calcium hydroxide . Lime water is obtained by filtering milk of lime . When transit through it, the carbon monoxide turbid :\n\nCa (OH) 2 + carbonic acid gas CaCO3 + H2O\n\ngypsum\n\n at that place are some(prenominal) types of gypsum - a intrinsic , burned-out and teetotal . Burnt gypsum or plaster of capital of France is obtained by heating system gypsum to a temperature one hundred fifty - 180 C. If the onyx marble mix with water , it turns semi-solid plastic big bucks that hardens quickly collectable to addition of water .
