Applications of coordination

compounds In electroplating​

Answer 1

$\huge\boxed{\fcolorbox{blue}{yellow}{Answer :-}}$

Usually stable coordination complexes on dissolution dissociate to small extent and furnish a controlled supply of metal ions. The metal ions when reduced clump together to form the clusters or nanoparticles. When the coordination complexes are used the ligands in the complex keep the metal atoms well separated from each other. These metal atoms tend to form a protective layer on the surface. Certain cyanide complexes K[Ag(CN)$\downward{2}$and K[Au(CN)$\downward{2}$] find applications in the electroplating of these noble metals.
