What will happen if we pour zinc oxide in copper sulphate

Open in App

Solution

The zinc displaces the copper from the copper sulfate:

CuSO4 + Zn = ZnSO4 + Cu

Change in Free Energy: ΔG(20C) = -206.6kJ (negative, so the reaction runs)

Change in Enthalpy: ΔH(20C) = -208.8kJ (negative, so the reaction is exothermic
