Why do acids not show acidic behaviour in the absence of water?

Explanation

### Step-by-Step Solution:

1. **Understanding Acids**: Acids are substances that can donate protons (H⁺ ions) when dissolved in a solvent, typically water.

2. **Role of Water**: Water acts as a solvent that facilitates the dissociation of acids. When an acid is added to water, it ionizes and releases hydrogen ions (H⁺).

3. **Dissociation of Acids**: For example, when hydrochloric acid (HCl) is dissolved in water, it dissociates into H⁺ ions and Cl⁻ ions:
