Identify the conjugate acid for each base. HS+ E. The conjugate acid of a base is always one proton (H⁺) more than the base itself, and that’s why H₂S is the correct answer. CH 3 COOH (aq) + NH 3 (aq) CH 3 COO − (aq) + NH 4+ (aq) Remember that a conjugated acid has one proton H+ more than the (conjugated) base of it. In aqueous solutions, hydrogen sulfide can undergo deprotonation to form the hydrosulfide ion, which is Explanation The conjugate base of a species is formed when the species donates a proton (H+). NH3 and NH4+ are a conjugate acid-base pair. In this case, HS⁻ is the conjugate base of H₂S. What is the conjugate acid and What is left behind when an acid donates a proton or a base accepts one?
