The salt formed when copper carbonate is added to sulfuric acid is copper sulfate. The chemical equation for this reaction is:

CuCO3(s) + H2SO4(aq) → CuSO4(aq) + H2O(l) + CO2(g)

In this reaction, the copper carbonate reacts with the sulfuric acid to form copper sulfate, water, and carbon dioxide gas. The copper sulfate is a soluble salt, which means that it will dissolve in the water. The carbon dioxide gas will escape into the atmosphere.
