Following two reactions can occur at cathode in the electrolysis of aqueous sodium chloride
`Na^(+) +e^(-) to Na(s), E_("red")^(Theta)=-2.71V`

Explanation

To solve the problem regarding the electrolysis of aqueous sodium chloride, we need to analyze the reactions that can occur at the cathode and their respective standard reduction potentials.

### Step-by-Step Solution:

1. **Identify the Reactions at the Cathode:**
The two possible reactions at the cathode during the electrolysis of aqueous sodium chloride are:
- Reduction of sodium ions:
\[ \text{Na}^+ + e^- \rightarrow \text{Na}(s) \quad E^\circ_{\text{red}} = -2.71 \, \text{V} \]
