Question 1

What does an electrolytic cell consist of?

Answer 1

Two electrodes, an electrolyte, and an external battery or power source

Question 2

What process does an electrolytic cell use?

Answer 2

Electrolysis

Question 3

What is electrolysis?

Answer 3

The process of supplying electrical energy to force a non-spontaneous redox reaction to occur

Question 4

What does the external power supply do in an electric cell?

Answer 4

It acts as an electron pump by pulling electrons from the anode and pushing them to the cathode

Question 5

What is an example of a secondary cell?

Answer 5

A rechargeable cell like nickel-cadmium

Question 6

Why was it difficult produce metals from their compounds by electrolysis?

Answer 6

Many ionic compounds have low solubility in water and water is a stronger oxidizing agent than the metal cations

Question 7

What does the production of active metals from minerals typically involve?

Answer 7

The electrolysis of molten compounds

Question 8

How is Aluminum produced?

Answer 8

Scientists were able to dissolve the aluminium in a mineral called cryolyte. The cryolite acts as an inert solvent for electrolysis. This forms a molten compound where aluminum can be produced electrolytically
