The reaction between copper sulfate (CuSO4) and hydrochloric acid (HCl) results in the formation of copper chloride (CuCl2) and sulfuric acid (H2SO4). The chemical equation for this reaction is:

CuSO4 + 2HCl → CuCl2 + H2SO4

In this reaction, the copper sulfate reacts with the hydrochloric acid to form copper chloride and sulfuric acid. The copper chloride is a green-colored compound that is soluble in water, while the sulfuric acid is a colorless, corrosive acid. This reaction is typically carried out in a laboratory setting and is used to produce copper chloride for various applications.
