| 摘 要： | 采用波波夫型外套等温量热计,已测得一级标准KCl在水中的积分溶解热为ΔH298=17532J/mol±0.1%.此结果与米献科报导的结果相一致,证明此仪器本身是可靠的.用此仪器测得La(NO3)3·6H2O在乙醇中的积分溶解热为ΔH298=9.713±0.2KJ/mol.

| Abstract: | The integral heat of solution of KGl (1 class, standard grade) in water was measured by using the Popoff's isothermal jacket calorimeter. The value obtained is △H = 17523J/mol ± 0.1%. This result is in agreement with that reported by P. K. Mishenko & proves that the instrument used is reliable. By using this instrument, the integral heat of solution of La(NO3)3·6H2Oin ethanol was measured to be△H= 9.713±0.2KJ/mol. |
