What is the main purpose of an ion-exchange membrane or a salt bridge in electrolysis?

To provide additional ions for the electrolysis process

To increase the flow of electricity through the electrolyte

To prevent the products from diffusing near the opposite electrode (correct)

To enhance the speed of the electrolysis reaction

What are the components required to conduct electrolysis?

Electrolyte, electrodes, and ion-exchange membrane

Electrolyte, electrodes, and an external power source (correct)

Electrolyte, cathode, and anode

Electrolyte, electrodes, and a partition

What happens to cations and anions during electrolysis?

Cations and anions combine to form a new compound

Cations and anions remain unchanged

Cations are reduced at the cathode, and anions are oxidized at the anode (correct)

Cations are oxidized at the cathode, and anions are reduced at the anode
