Chemistry - Metallurgy Question with Solution | TestHub

Amine complexes of gold are not stable, so, they cannot be used as a solvent.Moreover, in electroplating with silver, silver cyanide is used as electrolyte because the cyanide ion,$\mathrm{C}{\mathrm{N}}^{-}$, reacts with silver ion,$\mathrm{A}{\mathrm{g}}^{+}$to form the complex ion$\mathrm{A}\mathrm{g}(\mathrm{C}\mathrm{N}{)}_2^{-}$. This produces a silver and more adherent silver plating.
