The blue color of the solution on the far right indicates the presence of copper ions. The reaction may be split into its two half-reactions. Half-reactions separate the oxidation from the reduction, so each can be considered individually.

WebThe origin of the potential difference between the two electrodes may be traced to the relative tendencies of zinc and copper, or any other metal to go into solution as ions. Zinc has a greater tendency to form ions than copper; that is why this familiar fact that when a zinc rod is dipped into a copper sulphate solution a deposit of copper metal is obtained.
