Vedclass · Answer

(A) In the electroplating of gold and silver,cyanide complexes are used to ensure a smooth and uniform deposition of the metal.Specifically,the dicyanoaurate$(I)$ ion,$[Au(CN)_2]^-$,is used for gold plating.Similarly,the dicyanoargentate$(I)$ ion,$[Ag(CN)_2]^-$,is used for silver plating.Both are stable,soluble coordination complexes that provide a low concentration of free metal ions,which is essential for high-quality electroplating.

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