Question
Why cannot we store AgNO3 solution in copper vessel?
Solution
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.
\[\ce{Cu + 2AgNO3 ->\underset{Silver}{2Ag} + \underset{Copper nitrate}{Cu(NO3)2}}\]
