  1. Which of the following is true about an electrolytic cell?

It changes electrical energy into chemical energy.

It is the type of cell used in electroplating

It uses an electric current to make a nonspontaneous reaction go.

All of the above

  1. The products formed in the net reaction of the electrolysis of water are ____.

aqueous hydrogen ion and hydroxyl ion

hydrogen gas and oxygen gas

liquid hydrogen and oxygen gas

liquid oxygen and hydrogen gas

  1. What occurs in electroplating?

decomposition of a metal layer

decomposition of a salt layer

deposition of a metal layer on a material

deposition of a salt layer on a metal

Verified Answer :

The correct answers are:

17. All of the above
18. hydrogen gas and oxygen gas
19. deposition of a metal layer on a material

Electrolytic cells use electric currents to drive a non-spontaneous reaction forward. This is also used in electroplating which involves the movement of metal cations to the surface of another metal. Water can also undergo electrochemical reactions by splitting it into its gaseous components, hydrogen and oxygen.
