H3O+ ions act as?
Correct answer: D. Acid
- A. Base
- B. Catalyst
- C. Buffer
- D. Acid
Explanation
In the Brønsted-Lowry definition of acids and bases, an acid is a proton (H⁺) donor. Since, H3O+ ion has an extra H+ ion. Thus, it acts as an acid.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
