Bronsted-lowery Acids and Bases

Acid-Base Answer.5.

a. HSO₄^- and SO₄^2- represent a conjugate acid-base pair (HSO₄^- is the acid, SO₄^2- is the bae; they differ by one proton.)

b. HBr and Br^- represent a conjugate acid-base pair (HBr is the acid, Br^- is the base; they differ by one proton.

c. H₂PO₄^- and PO₄^3- are not a conjugate acid-base pair; they differ by two protons ( H₂PO₄^- is the conjugate acid of HPO₄^2- and also the conjugate base of H₃PO₄; HPO₄^2- is the conjugate acid of PO₄^3-).

d. HNO₃ and NO₂^- are not a conjugate acid-base pair; they differ by an oxygen atom as well as a prton (NO₃^- is the conjugate base of HNO₃; NO₂^- is the conjugate base of HNO₂.
