Question

a copper coin is kept in a solution of silver nitrate for some time what will happen to the coin and the color of the solution

Answer 1

Answer:

Copper metal is more reactive than silver metal thus, when copper coin is kept immersed in silver nitrate solution for some time, it displaces silver from silver nitrate solution.

Explanation:

The reaction is :

Cu + 2AgNO3 ---> Cu(NO3)2 + 2Ag

The grey solid crystal of Ag metal are seen growing on the copper coin and solution turns blue in colour

Answer 2

Answer: As we know that in the reactivity series copper is above silver so it will displace silver from its solution.

AgNO3 + Cu = CuSO4 + Ag

And you will notice that white silver will start accumulating on the copper coin. As Cu has now displaced Ag so it is now in the solution and the colour of the solution has been turned to Blue......

Hope it helps......
