Understanding Half

In this equation the copper(II) ion is being reduced {2+ 0} When we balance a half-reaction we first balance the mass of the participating species (atoms ions or molecules) and then the charge In this case the mass is balanced by adding a copper (atom or ion) to each side To balance the charge electrons are added
