Arrange the following in the increasing order of acidic strength.
Acetic acid, water and hydrochloric acid.

Explanation

To arrange the acids in increasing order of acidic strength, we need to understand the dissociation of each substance in water and their ability to donate hydrogen ions (H⁺).

### Step-by-Step Solution:

1. **Identify the Acids:**
- We have three substances: Acetic acid (CH₃COOH), water (H₂O), and hydrochloric acid (HCl).

2. **Understand Acid Strength:**
