Which of the following is the conjugate base of acetic acid (CH₃COOH)? A) H₃O⁺ B) CH₃COOH₂⁺ C) CH₃COO⁻ D) OH⁻

Question

Quizplus · Accepted Answer

The conjugate base of a compound is formed when it loses a hydrogen ion (H+). In the case of acetic acid, the hydrogen ion is lost from the carboxyl group (-COOH), leaving behind the acetate ion (-COO-). Thus, the answer is option C, which represents the acetate ion. Option A is incorrect because it represents the hydrosulfate ion (HSO4-). Option B is incorrect because it represents a compound with both the carboxyl and hydroxyl groups, which is not the conjugate base of acetic acid. Option D is incorrect because it represents the hydroxide ion (OH-), which is not related to acetic acid at all.
