Chemistry Question on coordination compounds
In the silver plating of copper, K[AG(CN)2] is used instead of AgNO3. The reason is :-
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 cannot displace Ag from [Ag(CN)2]− ion
Answer
less availability of Ag+ ions, as Cu cannot displace Ag from [Ag(CN)2]− ion
Explanation
Solution
In the silver plating of copper, K[Ag(CN)2]is used instead of AgNO3. The reason is less availability of Ag+ ions, as Cu cannot displace Ag from [Ag(CN)2]− ion.
