Question

Mr. Ramu wants to electroplate his chain with Nickel to prevent rusting. For the electroplating.

Give the reaction at the cathode.

Answer 1

Electroplating is a process of coating superior metals on the surface of some inferior metals.

At the cathode electrode reduction or acceptance of electron is happening.

1. Here Nickel ions accept electrons to produce Nickel metal at the cathode.
2. And the cathode here is is the chain that need to be electroplated.
3. So the cathode reaction is,

$N{i}^{2+}(Nickelion)+2e^{-}\to Ni\left(Nickel\right)$
