Please answer this question:-

Q. A copper coin is kept immersed in a solution of silver nitrate for some time.

What will happen to the coin and the colour of the solution?​

Answer 1

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.
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

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.
