Problem
Calcium chloride is much more soluble in water at 25 °C than magnesium chloride even though their standard enthalpies of solution are nearly identical (about −82 kJ·mol⁻¹). In one or two sentences, explain how differences in entropy of dissolution can account for this discrepancy in solubility.
