प्रश्न
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.
उत्तर
When the copper plate is dipped in AgNO3 solution, silver from the solution gets deposited on the copper plate. This happens because copper is a more reactive metal than silver and it displaces silver from the silver nitrate solution.
2AgNO3(aq) + Cu(s) → Cu(NO3)2(aq) + 2Ag(s)
