Question

Why cannot we store AgNO₃ solution in copper vessel?

Answer 1

Copper is above silver in the electrochemical series and is thus more reactive than silver. So, copper displaces silver from silver nitrate. Hence, we cannot store AgNO₃ solution in copper vessel.

\[\ce{Cu + 2AgNO3 ->\underset{Silver}{2Ag} + \underset{Copper nitrate}{Cu(NO3)2}}\]
