摘要

The isopiestic method has been used to determine the osmotic coefficients of the binary solutions MgBr2(aq) (from 0.4950 to 2.5197 mol · kg-1) at the temperature T = 323.15 K. Sodium chloride solutions have been used as isopiestic reference standards. The solubility of the bromide minerals in the mixed system (m1KBr + m2MgBr 2)(aq) has been investigated at T = 323.15 K by the physico-chemical analysis method. In addition to simple salts {KBr(cr) and MgBr2 · 6H_2O(cr)
