Question
A copper plate was dipped in AgNO3 solution. 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.

Solution
When the copper plate is dipped in an AgNO3 solution, silver from the solution gets deposited on the copper plate. This happens because copper is more reactive than silver and displaces silver from the silver nitrate solution.
\[\ce{Cu_{(s)} + 2AgNO3_{(aq)} -> Cu(NO3)2_{(aq)} + 2Ag_{(s)}}\]
