Abstract
The solubilities of the system LiBr−MgBr2−H2O have been investigated at 25°C and 50°C. It is established that the system is of a simple eutonic type. Pitzer's model is used for calculating the thermodynamic functions needed for plotting the solubility isotherms of the systems LiX−MgX2−H2O (X=Cl, Br) at 25°C. According to calculations made, the Gibbs energy of formation of LiCl·MgCl2·7H2O from simple salts is ΔrG°m=−2.01 kJ-mol−1, while the value ΔfG°m=−2748 kJ-mol−1 corresponds to formation from the elements.
