WebIn a displacement reaction, the more reactive metal displaces the ions of the less reactive metal from solution. They are all redox reactions as they involve the transfer of electrons. Full, ionic and half equations can be written for all these displacement reactions, for example: Balanced equation: Mg (s) + CuSO4 (aq) → MgSO4 (aq) + Cu (s ... WebFor the half equation: Al 3+ + 3e-→ Al, this is described as a reduction reaction as aluminium ions are gaining electrons and the gain of electrons is reduction.

WebCu ---> Cu 2+ + 2e¯ Here is the rule to follow: the total electrons MUST cancel when the two half-reactions are added. Another way to say it: the number of electrons in each half-reaction MUST be equal when the two half-reactions are added. What that means is that one (or both) equations must be multiplied through by a factor. Webelectrochemical cells. For example the reaction, Zn(s) + Cu 2+ (aq) → Zn 2+ (aq) + Cu (s), can be separated into two half-reactions that form the basis of the electrodes in an electrochemical cell.
