9.4.2c Electrolytic Cells III (T/F)

The concentration of ions in the electrolyte does not affect the type of species that will be oxidized at the anode.

In aqueous solution, ions from the electrolyte and water molecules can be oxidized at the anode.

The concentration of sodium ions in sodium chloride solution affects the selection of ions to be reduced at the cathode.

Na⁺ is more easily reduced than water in aqueous sodium chloride solution.

Cations and anions in aqueous solution can be reduced or oxidized at the electrodes.

The oxidation rate on a copper electrode is higher than on a silver electrode in copper(II) nitrate solution.

Electrodes are coated with a less reactive metal during the electroplating process.

In the purification of copper, impure copper is made the anode and pure copper is made the cathode.

The electrolyte used in the purification of copper is aqueous copper(II) sulfate solution.

Copper is widely used to make wires because it is a good conductor of electricity.
