Lime is a term that includes calcium oxide (cao, also called quicklime) and calcium hydroxide (ca(oh)2 also called slaked lime). it is used in the steel industry to remove acidic impurities, in air-pollution control to remove acidic oxides such as so2, and in water treatment. slaked lime is produced by treating quicklime with water: cao(s) + h2o(l) → ca(oh)2(s)δh o = −65.2 kj/mol given the standard enthalpies of formation of cao and h2o are −635.6 kj/mol and −285.8 kj/mol, respectively, calculate the standard enthalpy of formation of ca(oh)2.
