The demixing phenomenon of the system′s at below room temperature was observed. The precise demixing composition and composition of double-saturated point of the system have been determined. A unique effect, namely additive property between MgSO 4 and Li 2SO 4 has been observed and explained in terms of "pseudo-ternary system" concept. An empirical formula has been worked out to correlate the mutual solubility.展开更多
