Silver plated vessels and gold plated ornaments are made by _________ method.
Silver plated vessels and gold plated ornaments are made by _________ method.
The explanation for the correct option:
Option(A) Electroplating
- Electroplating is basically the process of plating a metal onto the other by hydrolysis mostly to prevent corrosion of metal or for decorative purposes.
- The process uses an electric current to reduce dissolved metal cations to develop a lean coherent metal coating on the electrode.
- Electroplating is often applied in the electrical oxidation of anions on a solid substrate like the formation of silver chloride on silver wire to form silver chloride electrodes.
- Electroplating is majorly applied to modify the surface features of an object (e.g corrosion protection, lubricity, abrasion).
The explanation for the incorrect option:
(B) Anodizing- Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.
(C) Galvanizing- Galvanizing is a corrosion protection process for steel or iron, in which the substrate is coated with zinc to prevent it from rusting.
(D) Tinning- Tinning is the process of thinly coating sheets of wrought iron or steel with tin, and the resulting product is known as tinplate
Hence,Option(A) Electroplating is the correct option. Silver plated vessels, gold plated ornaments are made by electroplating
