In the present work, we report the studies concerning liquid‐liquid‐solid equilibria for the ternary system sodium thiosulphate (Na 2 S 2 O 3 )+ t ‐butanol+water at ambient pressure and at room temperature (303±2 K). The solubility data of Na 2 S 2 O 3 are reported for solutions in water, t ‐butanol and solutions of varying concentrations of t‐ butanol in water. The phase diagram for the said system is developed, described and compared with similar systems studied such as Na 2 S 2 O 3 +ethanol+water, K 2 CO 3 +methanol+water, etc . These results have been explained in terms of structural properties of aqueous t‐ butanol solutions and further discussed in terms of the effect of ions to cause phase separation.
