Abstract
The solubilities of the system LiBr-MgBr2-H2O have been investigated a t 25-degrees-C and 50-degrees-C. It is established that the system is of a simple eutonic type. Pitzer's model is used for calculating the t hermodynamic functions needed for plotting the solubility isotherms of the systems LiX-MgX2-H2O (X = Cl, Br) at 25-degrees-C. According to c alculations made, the Gibbs energy of formation of LiCl.MgCl2.7H2O fro m simple salts is DELTA(r)G(m)o = -2.01 kJ-mol-1, while the value DELT A(f)G(m)o = -2748 kJ-mol-1 corresponds to formation from the elements.
