Summary, etc. <p><span lang="EN-GB">The liquid-liquid and liquid-liquid-solid equilibria for the ternary <em>t</em>-butanol-water-Na<sub>2</sub>SO<sub>3</sub>/Na<sub>2</sub>SO<sub>4</sub> system is reported at ambient pressure and at 298</span><span lang="EN-GB">±</span><span lang="EN-GB">2 K. The solubility data of solutions of Na<sub>2</sub>SO<sub>3</sub>/Na<sub>2</sub>SO<sub>4</sub> in water, <em>t-</em>butanol and solutions of varying compositions of <em>t-</em>butanol in water are reported. The phase diagrams for the studied systems are developed and salting-out effect of salt anion has been described. The structural properties of aqueous <em>t-</em>butanol solutions and the salting-out effect of SO<sub>3</sub><sup>2-</sup><sub> </sub>and<sub> </sub>SO<sub>4</sub><sup>2-</sup><sub> </sub>ions to cause phase separation have been explained. The salting-out ability of Na<sub>2</sub>SO<sub>3</sub> is higher than that of Na<sub>2</sub>SO<sub>4 </sub>since the Gibbs free energy of hydration (Δ<em>G</em><sub>hyd</sub>) of SO<sub>4</sub><sup>2-</sup> <br /> (−1080 kJ mol<sup>-1</sup>) is lower than that of SO<sub>3</sub><sup>2-</sup> (−1295 kJ mol<sup>-1</sup>) ion.</span></p>
