Question

In this equilibrium, hydroxide ion acts as a A) Lewis base B) Bronsted base C) both A & B D) neither A or B

Answer 1

Answer:

(b) Bronsted base

Explanation:

The hydroxide ion is formed when $H_2O$ losses $H^+$ ion

We know hat the compound which losses $H^+$ is known as the bronsted acid and the ion which is formed after losing $H^+$ is known as bronsted base

As the hydroxide ion is formed after losing the hydrogen ion from $H_2O$ so it is a bronsted base.
