If a Strong Acid Were to Add H⁺ to the Intracellular

Multiple Choice

If a strong acid were to add H⁺ to the intracellular fluid, the effect would most likely be buffered, because

A) HPO₄^2- would act as a weak acid and donate an H⁺ to become PO₄^-.
B) HPO₄^2- would act as a weak base and accept an H⁺ to become H₂PO₄^-.
C) H₂PO₄^- would act as a weak acid and accept an H⁺ to become H₃PO₄^-.
D) PO₄ would act as a strong base and accept an H⁺ to become HPO₄.
