_​

Answer 1

Dear Student,

Dissolution of anhydrous salts in water are exothermic reaction. Therefore, dissolution of anhyd. CuSO₄ in water will also be exothermic reaction i.e. heat will be released in the reaction.

${\mathrm{CuSO}}_4\left(\mathrm{s}\right)+\hspace{0.17em}{\mathrm{H}}_2\mathrm{O}\to {\mathrm{Cu}}^{2+}\left(\mathrm{aq}\right)+{{\mathrm{SO}}_4}^{2-}\left(\mathrm{aq}\right)$
