Which of the following is the conjugate acid of hydrogen phosphate, HPO₄²^-? A)H₂PO₃^- B)H₂PO₄^- C)H₃PO₄ D)H₂PO₄²^- E)none of the above

Question

Quizplus · Accepted Answer

The conjugate acid of hydrogen phosphate (HPO4^2-) is the species that forms when it gains a hydrogen ion (H+). This results in the formation of dihydrogen phosphate (H2PO4^-). The correct formula for dihydrogen phosphate is H₂PO₄^-, which matches option B. Option A has an incorrect charge on the phosphate ion, option C is missing a hydrogen ion, and option D includes additional phosphate ions. None of the options include the correct charge balance for the species.
