Out of aluminium and silver vessel, which one will be more suitable to store 1 M HCl solution and why ?
`E_(Al^(3+)|Al)^@=-1.66V, E_(Ag^(+)|Ag)^@ =+0.80V`

Explanation

To determine which vessel, aluminum or silver, is more suitable for storing a 1 M HCl solution, we need to analyze the standard reduction potentials of both metals in relation to the hydrogen ion (H⁺) reduction potential.

### Step-by-Step Solution:

1. **Identify Standard Reduction Potentials**:
- The standard reduction potential for aluminum (Al³⁺/Al) is given as \( E^\circ = -1.66 \, V \).
- The standard reduction potential for silver (Ag⁺/Ag) is given as \( E^\circ = +0.80 \, V \).
- The standard reduction potential for the hydrogen ion (H⁺/H₂) is taken as \( E^\circ = 0 \, V \).
