摘要：
The curves of heating and cooling crystalline lanthanum nitrate were registered and numerical differentiation was carried out. The first derivatives of kinetic curves expressed as the temperature function make it possible to carry out comparative studies of dissolution and crystallization. Superposition of relative water concentration scale on the third derivative of heating and cooling curves make the analysis of stoichiometry and mechanism of hydration changes possible in the solid phase and saturated solutions.
