In the refining of silver, the recovery of silver from silver nitrate solution involved displacement by copper metal. Write down the reaction involved.
$\mathop {2AgN{O_{3(aq)}}}\limits_{Silver{\text{ }}nitrate} + \mathop {C{u_{(s)}}}\limits_{Copper} \to \mathop {Cu{{\left( {N{O_3}} \right)}_{2\left( {aq} \right)}}}\limits_{Copper{\text{ }}nitrate} + \mathop {2A{g_{(s)}}}\limits_{Silver} $
