Why is pure water neutral although it contains ` H_3O^(+) ` ions?

Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Understanding Pure Water**: Pure water is a neutral substance, which means it has a pH of 7. This indicates that it is neither acidic nor basic. 2. **Presence of Ions**: In pure water, there are hydronium ions (H₃O⁺) present. These ions are formed when water molecules dissociate slightly into hydrogen ions (H⁺) and hydroxide ions (OH⁻). 3. **Nature of Hydronium Ions**: Hydronium ions (H₃O⁺) are considered to be slightly acidic. This means that if they were present in isolation, they would contribute to acidity in a solution. ...
