A half-equation shows you what happens at one of the electrodes during electrolysis. Electrons are apparent as e-. A half-equation is counterbalanced by adding, or demography away, a cardinal of electrons according to the absolute cardinal of accuse on the ions in the equation.
When absolute metal ions (cations) access at the abrogating electrode (the cathode), they accretion electrons to anatomy aloof metal atoms. This is alleged reduction. For example:
Pb2 2e- → Pb
When abrogating non-metal ions (anions) access at the absolute electrode (the anode), they lose electrons to anatomy aloof atoms or molecules. This is alleged oxidation. For example:
2Br- → Br2 2e-
Cations go to the cathode. They allegation to accretion abundant electrons to accomplish them neutral. So an Al3 ion needs to accretion three electrons:
Al3 3e- → Al
Half-equations for non-metal anions are added difficult to balance. For example, chloride ions accomplish chlorine gas. Most non-metal elements formed in electrolysis are diatomic molecules (eg Cl2). For example:
Cl- → Cl2
Add in two electrons to antithesis the allegation so that both abandon accept the aforementioned charge. The two electrons allegation to go on the right-hand side, so that both abandon accept an all-embracing allegation of -2. For example:
2Cl- → Cl2 2e-
