C)pH unit.
D)proton.

Question

Quizplus · Accepted Answer

Conjugate acid-base pairs differ by a proton (H+). In the acid-base reaction, one species donates a proton (acid) and the other accepts that proton (base), forming a conjugate acid-base pair. The conjugate acid is the species formed when the base accepts the proton, and the conjugate base is the species remaining after the acid has donated the proton. Therefore, the correct answer is D: proton.
