Answer 2

Answer:

Sodium is the correct answer.

Explanation:

• Electroplating is an electrical process which uses electric current to reduce the metal into ions.

• This process is used to coat metal over another metal.

• The metal to be plated is used as cathode and pure metal is used as anode.

• This process is used to reduce corrosion and for decoration purpose.

• Sodium is alkali metal and it forms hydrogen gas when it is used as electrolyte. This makes sodium unsuitable for electroplating.
