Explanation:

Copper Sulphate is blue, not because of air, but because it has been oxidised to the Cu2+ ion which is a d-block metal ion. The electrons in the metal ion can transition between different energy states and therefore the ion absorbs light energy and can be seen as being BLUE.

✅✅✅✅✅

Copper sulphate solution contains Cu2+ ions and SO/ – ions together with H + and OH – ions from the water. During electrolysis, Cu2+ and H+ ions: migrate to the cathode, but only the Cu2+ ions are discharged. The H + ions remain in solution.
