According to the Bronsted-Lowry concept, which of the following species cannot function as an acid?
Correct answer: A. SO₄ ²⁻
- A. SO₄ ²⁻
- B. H₃O⁺
- C. HSO₄⁻
- D. NH₄⁺
Explanation
A Bronsted-Lowry acid is a proton (H⁺) donor. The sulfate ion (SO₄²⁻) does not have any protons to donate, so it cannot function as a Bronsted-Lowry acid.
