Salty water contains no free electrons but can conduct electricity. How?

Explanation

### Step-by-Step Solution:

1. **Understanding the Composition of Salty Water**:
- Salty water is a solution that contains dissolved salt (sodium chloride, NaCl). When salt dissolves in water, it dissociates into its constituent ions: sodium ions (Na⁺) and chloride ions (Cl⁻).

2. **Absence of Free Electrons**:
- Unlike metals, which conduct electricity through the movement of free electrons, salty water does not have free electrons. Instead, it relies on the movement of ions to conduct electricity.
