Why can we not use an aqueous solution of sodium chloride to isolate sodium metal by electrolysis ?

Explanation

To understand why we cannot use an aqueous solution of sodium chloride (NaCl) to isolate sodium metal through electrolysis, let's break down the process step by step:

### Step-by-Step Solution:

1. **Understanding Electrolysis**:
- Electrolysis is a process that uses electrical energy to drive a non-spontaneous chemical reaction. It typically involves the breakdown of ionic compounds into their respective elements or simpler compounds.

2. **Dissociation of Sodium Chloride**:
