Answer:
c. CH₃COO⁻
Step-by-step explanation:
The task is not very clear but I think this is the original question.
Identify the conjugate base of CH₃COOH in the reaction:
CH₃COOH + HSO₄⁻ ⇄ H₂SO₄ + CH₃COO⁻
a. HSO₄⁻
b. SO₄²⁻
c. CH₃COO⁻
d. H₂SO₄
e. OH⁻
Let's consider the following reaction
CH₃COOH + HSO₄⁻ ⇄ H₂SO₄ + CH₃COO⁻
According to the Bronsted-Lowry acid-base theory, an acid is a species that donates H⁺ and a base is a species that accepts H⁺.
CH₃COOH is an acid because it donates H⁺ to HSO₄⁻, whereas CH₃COO⁻ is its conjugate base, because it accepts H⁺ from H₂SO₄ to form CH₃COOH.
Another acid-base pair is H₂SO₄/HSO₄⁻
