Options

(a) a thin layer of Ag is formed on Cu
(b) more voltage is required
(c) Ag⁺ ions are completely removed from solution
(d) less availability of Ag⁺ ions,as Cu can not displace Ag from [Ag(CN)₂]⁻ ion

Correct Answer:

less availability of Ag⁺ ions,as Cu can not displace Ag from [Ag(CN)₂]⁻ ion
