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.
