Question

What will happen when a copper coin is placed in a solution of silver nitrate. Give reasons for your answer.

Answer 1

When a copper(Cu) coin is placed in a solution of silver nitrate (AgNO3).The solution become blue due to the formation of copper nitrate(Cu(NO)3) and a Shiny greyish white deposit of silver (Ag) is form on the copper(Cu) coin.Copper (Cu) being more reactive than silver(Ag). Hence copper(Cu) will displace a silver(Ag) from its Solution.


The balanced chemical reaction is given below:

Cu (s)+ 2AgNO3(aq)-----> Cu(NO)3 +2Ag(s)

Answer 2

Hi friend,

Your answer:

When copper coin is placed in a solution of silver nitrate,a shiny grayish white deposit of silver is formed on the copper coin and the solution turns blue in colour.

Reason:- Copper metal being more reactive than silver,displaces silver from silver nitrate solution.

Equation:-
Cu (s)+ 2AgNO3 (aq)  ->  Cu(NO)^3 (aq) + 2Ag (s)

Hope it helps!
