Comment upon `H_(2)O` as an Arrhenius acid/base ,Bronsted-Lowry acid/base and Lewis acid /base.

Explanation

To analyze water (H₂O) as an Arrhenius acid/base, Bronsted-Lowry acid/base, and Lewis acid/base, we can break down the definitions and apply them to water step by step.

### Step 1: Arrhenius Acid/Base
- **Definition**: An Arrhenius acid is a substance that increases the concentration of H⁺ ions in aqueous solution, while an Arrhenius base increases the concentration of OH⁻ ions.
- **Application to H₂O**: Water can dissociate into H⁺ and OH⁻ ions:
\[ H_2O \rightleftharpoons H^+ + OH^- \]
