Question

For Cathodic deposition which of the following statements is appropriate?

(a) The charge is not balanced in the process of Cathodic deposition

(b) Esterification take place in the electrolyte solution

(c) The charge is balanced in the process of Cathodic deposition

(d) Oxidation and reduction take place in the electrolyte solution but not in the electrodes

The question was posed to me in a dream while sleeping

I'd like to ask this question from Preparation of Thin Films topic in portion Preparative Methods of Solid State Chemistry

Answer 1

The correct option is (c) The charge is balanced in the process of Cathodic deposition

Explanation: In Cathodic deposition, which is a method of electroplating with the application of external field, the charges are always balanced and in order to balance the charges in the process, the anodic metal gradually dissolves in the electrolyte.
