An aqueous solution of silver nitrate..........be stored in a copper vessel.

Explanation

To solve the question, we need to fill in the blank in the statement: "An aqueous solution of silver nitrate..........be stored in a copper vessel."

Let's analyze the situation:

1. **Understanding the Reaction**: When an aqueous solution of silver nitrate (AgNO₃) is placed in a copper vessel, we need to consider the electrochemical properties of silver and copper. Silver ions (Ag⁺) can be reduced to silver metal, while copper (Cu) can be oxidized to copper ions (Cu²⁺).

2. **Reduction Potentials**: The reduction potentials for these metals are:
- Silver (Ag⁺ + e⁻ → Ag) has a standard reduction potential of +0.80 V.
