Question

Show by means of a fully labeled diagram how you would electroplate a silver coin with copper, given a solution of copper (II) nitrate. Write an ionic equation to represent the reaction taking place at the anode.

Answer 1

Reaction:-

Cu + 2 AgNO₃(aq) $\to$ 2 Ag + Cu(NO₃)₂(aq)

One metal replaces another metal in a compound dissolve in water

Copper is placed in aqueous silver nitrate

Crystals made a silver accumulate on the copper bar

Ionic Equation :-

Cu(s) + 2 Ag⁺(s) + 2NO₃^- (aq) $\to$ Cu²⁺(aq) + 2NO₃^- (aq) + 2 Ag (s)
