Question

Why do we add sulfuric acid in the solution of cuso4

Answer 1

The sulfuric acid will dissolve any residual copper metal or any copper oxides that exist as impurities in the copper sulfate, converting those impurities into copper sulfate.

H2SO4(aq)+Cu(s)⟶CuSO4(aq)+H2(g)

HX2SOX4(aq)+Cu(s)⟶CuSOX4(aq)+HX2(g)H2SO4

(aq)+CuO(s)⟶CuSO4(aq)+H2O(l)

HX2SOX4(aq)+CuO(s)⟶CuSOX4(aq)+HX2O(l)2H2SO4

(aq)+Cu2O(s)⟶2CuSO4(aq)+H2O(l)+H

2(g) 2HX2SOX4(aq)+CuX2O(s)⟶2CuSOX4(aq)+HX2O(l)+HX2(g)
