Question

A process of electroplating, in which metals ions from the solutions are deposited on the cathode as a thin film in the presence of an applied external field is known as____________

(a) Electroless deposition

(b) Cathodic deposition

(c) Anodic oxidation

(d) Thermal oxidation

I got this question by my school teacher while I was bunking the class.

My question is based upon Preparation of Thin Films in section Preparative Methods of Solid State Chemistry

Answer 1

Correct choice is (b) Cathodic deposition

Explanation: Cathodic deposition is a standard method of electroplating where two metals electrodes are dipped into an electrolyte solution and on application of an external field across the electrodes, metal ions from the solution are deposited on the cathode as a thin film.
