Question
Why cannot we store $AgNO_3$​​​​​​​ solution in copper vessel?
✓

Answer

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 $AgNO_3$​​​​​​​ solution in copper vessel.
$​​​​​​​Cu + AgNO_3 \rightarrow Cu(NO_3)_2 + 2Ag$
