Question

H₂S + H₂O --> HS^- + H₃O⁺ In the reaction above, what is the conjugate base of H?S?

Quizplus · Accepted Answer

A conjugate acid/base pair is a pair of two compounds that differ only in the presence of a proton. The conjugate acid of a base is that base with one additional proton. The conjugate base of an acid is that acid with one less proton. In the context of the question, the conjugate base of H?S is the species with one less proton, HS-.
