Chapter 10, Problem 10.49PAE

Calculate $\Delta S°$ for the dissolution of magnesium chloride: ${\text{MgCl}}_{\text{2}}\text{(s)}\to {\text{Mg}}^{\text{2+}}(\text{aq})+2{\text{Cl}}^{{}^{\_}}(\text{aq})$ . Use your understanding of the solvation of ions at the molecular level to explain the sign of $\Delta S°$ .
