Question

The electrolyte used in the Electroplating of an article with Nickel is _____.

Answer 1

1. Nickel has exceptional ductility, corrosion resistance, and hardness, making it suitable for electroplating metal.
2. Numerous industrial uses need nickel plating.
3. Aqueous nickel sulphate solution serves as the electrolyte.
4. The nail is the cathode, while the anode is a block of nickel metal.

Reaction at the cathode:

${\mathrm{Ni}}^{2+}+2{\mathrm{e}}^{-}\to \mathrm{Ni}\left(\mathrm{s}\right)$

Reaction at the anode:

$\mathrm{Ni}\left(\mathrm{s}\right)–2{\mathrm{e}}^{-}\to {\mathrm{Ni}}^{2+}$

Hence, the electrolyte used in the Electroplating of an article with Nickel is ${\mathrm{Ni}}^{2+}$.
