在大约1mol·dm-3的盐酸水溶液中测定了K2O·MgO·6B2O3·10H2O的溶解焓。结合已获得的其它热化学数据,得出K2O·MgO·6B2O3·10H2O的标准摩尔生成焓为-(12250.35±9.68)kJ·mol-1,并利用“基团贡献法”计算出标准摩尔吉布斯自由能为-11103kJ·mol-1。从而计算出其标准摩尔生成熵和标准摩尔熵。
The enthalpy of dissolution of K2O · MgO · 6B2O3 · 10H2O was measured in an aqueous hydrochloric acid solution of about 1 mol · dm-3. Combined with other thermochemical data obtained, the standard molar enthalpy of formation of K2O · MgO · 6B2O3 · 10H2O was found to be - (12250.35 ± 9.68) kJ · mol-1, and the “group contribution method” was used to calculate The standard molar Gibbs free energy is -11103 kJ · mol-1. Thus, the standard molar entropy and the standard molar entropy were calculated.
