In electroplating of copper, K[Ag(CN)2] is used instead of AgNO3. The reason is:
- a thin layer of Ag is formed on Cu.
- more voltage is required.
- Ag+ ions are completely removed from solution.
- less availability of Ag+ ions, as Cu cannot displace Ag from [Ag(CN)2]- ion.
Answer
(D) less availability of Ag + ions, as Cu cannot displace Ag from [Ag(CN) 2 ] - ion.
