Why does an aqueous solution of an acid conduct electricity?

Explanation

**Step-by-Step Solution:**

1. **Understanding Acids in Aqueous Solution**: When an acid is dissolved in water, it forms an aqueous solution. For example, sulfuric acid (H₂SO₄) when mixed with water becomes H₂SO₄ (aq).

2. **Dissociation of Acids**: In an aqueous solution, acids dissociate into ions. For instance, sulfuric acid dissociates into hydrogen ions (H⁺) and sulfate ions (SO₄²⁻). The dissociation can be represented as:
\[ H₂SO₄ (aq) \rightarrow 2H⁺ (aq) + SO₄²⁻ (aq) \]
