MCQOPTIONS

1.	In the silver plating of copper, \[K[Ag{{(CN)}_{2}}]\] is used instead of \[AgN{{O}_{3}}\]. The reason is
A.	a thin layer of Ag is formed on Cu
B.	more voltage is required
C.	\[A{{g}^{+}}\] ions are completely removed from solution
D.	less availability of \[A{{g}^{+}}\] ions, as Cu cannot displace Ag from \[{{[Ag{{\left( CN \right)}_{2}}]}^{-}}\] ion
