Question

Describe an experiment for the electroplating of an iron objects with copper.​

Answer 1

Experiment:

Aim: Electroplating an iron article with copper

Apparatus: Iron article, copper wire/strip, wire, battery, glass, Dil. copper sulphate solution.

Procedure:

• Connect the copper wire to the cathode and iron article to the anode.

• Place both of them in the glass ensuring that they do not touch each other.

• Pour dilute copper sulphate solution (electrolyte) in the glass and switch in the battery.

• A low voltage for a longer time will be preferred as the coating will be uniform and will not come off easily.

Reactions:

Cathode: Cu --> Cu2+ + 2e-

Anode: Cu2+ + 2e- --> Cu
