The strongest conjugate base is:
Correct answer: D. CH₃COO⁻
- A. NO₃⁻
- B. Cl⁻
- C. SO₄ ²⁻
- D. CH₃COO⁻
Explanation
The strength of a conjugate base is inversely related to the strength of its acid. Since acetic acid (CH₃COOH) is the weakest acid among the choices, its conjugate base, the acetate ion (CH₃COO⁻), is the strongest.
