Answer 1

Answer:

A layer of silver will form and solution turns blue.

Explanation:

As we know copper is at higher place in reactivity series than silver. And highly reactive element acts

as reducing agent. So when we put copper coin in

silver solution. Copper replaces the silver in the solution and make a silver layer on the coin. And the color of solution turns blue due to dissolution of copper in solution.
