Describe what happens to copper ions during electrolysis of copper sulphate.

Copper ions are positively charged. So they are attracted to the negative electrode. The negative electrode is called cathode.At the cathode, each copper ion gains two electrons. They are said to be reduced because reduction is the gain of electrons. The ionic equation for the reduction process:Cu2+ (aq) + 2e- --> Cu (s)Reduction of copper ion produces copper atom.
