Question

What is the conjugate acid in this reaction? hc2h3o2(aq)+h2o(l)⇌h3o++c2h3o−2(aq).

Answer 1

HC2H3O2(aq) + H2O(l) → H3O⁺(aq) + C2H3O2⁻(aq)

acid base acid base

Explanation: I f we consider the only forward reaction

H3O⁺ is the conjugate acid of the base H2O. For reverse reaction CH3COOH is the conjugate acid of the base CH3COO⁻.
