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

(b) Bronsted base

Step-by-step 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.
