Tin is widely used in eletrolytic baths for which process that forms a metal coating?
Tin(II) chloride:  SnCl is widely used as a reducing agent (in acid solution), and in electrolytic baths for tin-plating. Electroplating: Electroplating is a process that uses electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode.
