State two conditions necessary for the electroplating of an article with silver.
Original Khojo Papers practice question — not from a past board paper.
Answer
The article to be plated is made the cathode and a pure silver plate is made the anode. The electrolyte must be a soluble silver salt solution, and a low current density is used so that the deposit is smooth and adherent.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The electrolyte must contain ions of the plating metal so that the concentration of the solution stays constant.
