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.

Answer 1

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.

\[\ce{Cu_{(s)} + 2AgNO3_{(aq)} -> Cu(NO3)2_{(aq)} + 2Ag_{(s)}}\]
