Question

when copper is dipped in AgNO3 solution the colour of the solution changes to blue aftersometimes. which ion is responsible for the change in colour of AgNo3 solution to Blue after sometime. Only need to tell which ion is responsible ?​

Answer 1

Explanation:

hen the solution is diluted with water, water molecules displace the nitrate ions in the coordinate sites around the copper ions, causing the solution to change to a blue color.

copper ions is responsible

hope it helps

Answer 2

Answer:

Copper is more reactive than silver. Hence when copper wire is dipped in silver nitrate solution it displaces silver from silver nitrate (AgNO3 ) solution forming copper nitrate which is bluish green in color. This is a displacement reaction.
