Question

The electrolytes usually used in the electroplating of gold and silver, respectively, are : (A) [Au(OH)4]- and [Ag(OH)2]- (B) [Au(CN)2]- and [Ag Cl2]- (C) [Au(NH3)2]+ and [Ag(CN)2]- (D) [Au(CN)2]- and [Ag(CN)2]-

The Anode is a bar of silver metal, and the electrolyte (the liquid in between the electrodes) is a solution of Silver cyanide, [ Ag ( CN )2]-, in water. Gold plating is done in much the same way, using a gold anode and an electrolyte containing Gold cyanide, [ Au ( CN )2]-.

Q. The electrolytes usually used in the electroplating of gold and silver, respectively, are :

$[A u (O H)_{4}]^{-}$ and $[A g (O H)_{2}]^{-}$

$[A u (CN)_{2}]^{-}$ and $[A g C l_{2}]^{-}$

$[A u (N H_{3})_{2}]^{+}$ and $[A g (CN)_{2}]^{-}$

$[A u (CN)_{2}]^{-}$ and $[A g (CN)_{2}]^{-}$

The Anode is a bar of silver metal, and the electrolyte (the liquid in between the electrodes) is a solution of Silver cyanide, $[A g (CN)_{2}]^{-}$ , in water. Gold plating is done in much the same way, using a gold anode and an electrolyte containing Gold cyanide, $[A u (CN)_{2}]^{-}$ .
