Heat of Formation of Calcium Aluminate Monocarbonate at 25 °C

The heat of formation of 3CaO·Al(2)O(3)·CaCO(3)·10.68H(2)O at 25 °C was determined by the heat-of-solution method, with 2N HCl as the solvent and 3CaO·Al(2)O(3)·6H(2)O and CaCO(3) as the reactants. The heat of solution of CaCO(3), to form dissolved CO(2), was obtained by a new technique and a modifi...

description The heat of formation of 3CaO·Al(2)O(3)·CaCO(3)·10.68H(2)O at 25 °C was determined by the heat-of-solution method, with 2N HCl as the solvent and 3CaO·Al(2)O(3)·6H(2)O and CaCO(3) as the reactants. The heat of solution of CaCO(3), to form dissolved CO(2), was obtained by a new technique and a modified calculation which served to include the heat of vaporization of the gas escaping in the reaction and resulted in a higher value than those obtained by Wells and Tayıor and by Bäckström in determinations representing only partial solution of CO(2). The results obtained were: [Table: see text]
