Question

What is the purpose of Electro-plating? What electrolyte is used to plate gold on any substance?

WBBSE Class X Physical Science Electrolysis 03 Mark 2024

Answer

The purpose of electroplating is:

  1. To improve the appearance of the surface.
  2. To provide protection against corrosion, wear, and tear.

To plate gold on a substance, the electrolyte used is typically a solution containing gold chloride (AuCl3) or gold cyanide (Au(CN)2⁻).
