Give reasons for the following:
An aqueous solution of sodium chloride conducts electricity.

Explanation

To explain why an aqueous solution of sodium chloride (NaCl) conducts electricity, we can break down the process into several steps:

### Step-by-Step Solution:

1. **Understanding Solid Sodium Chloride**:
- Solid sodium chloride is made up of Na⁺ and Cl⁻ ions arranged in a lattice structure. In this solid state, the ions are fixed in place and cannot move freely.
- **Reason**: Since the ions are not free to move, solid NaCl does not conduct electricity.
