Quick questions on Electrolytic cells and Faraday's laws: VCE Chemistry Unit 3

An electrolytic cell has three components:

Only the cations and anions of the salt itself are present. The cation is reduced at the cathode; the anion is oxidised at the anode.

Water (H2O) is also present, and it can be reduced or oxidised in competition with the dissolved ions. To predict the product, compare reduction potentials of all possible reductions at the cathode (and oxidations at the anode), and choose the most likely (typically the species with the most positive reduction potential for cathode reduction, and the most negative reduction potential when reversed for anode oxidation).

Compare a galvanic cell and an electrolytic cell. State two similarities and two differences. [4 marks]
