The Role of Sulphuric Acid in Copper Plating - Finishing

The sulfuric acid in a copper electrolyte is there for two reasons, one is to keep the copper in solution, you only used a 0,1 m solution, if you use higher concentrations your copper sulfate will partially get Cu(OH) 2. Also the sulfuric acid gives you a better conductivity and with this comes a better throwing power.

Does sulfuric acid react with copper? - Quora

Copper does not react with dilute sulphuric acid as its reduction potential is higher than that of hydrogen. Copper does not displace hydrogen from non-oxidising acids like HCl or dilute H2SO4. But, concentrated sulphuric acid is an oxidising agent. So, when copper is heated with conc.H2SO4, a redox ...
