Question
A copper plate was dipped in $AgNO_3$​​​​​​​ After certain time, silver from the solution was deposited on the copper plate. State the reason why it happened. Give the chemical equation of the reaction involved.
✓

Answer

Silver gets deposited on the copper plate because copper is more reactive than silver and hence displaces silver from silver nitrate solution.
$2\text{AgNO}_3\text{(aq)}+\text{Cu(s)}\rightarrow\text{Cu(NO}_3)_2\text{(aq)}+2\text{Ag(s)}$
