Bronsted-lowery Acids and Bases

Acid-Base Answer.4.

a. H₃PO₄ and PO₄^3- do not represent a conjugate acid-base pair, since they differ from each other by more than one proton. the conjugate base of H₃PO₄ is the H₂PO₄^-; the conjugate acid of PO₄^3- is the HPO₄^2- ion.

b. HBr and BrO^- don't represent a conjugate acid-base pair, as they don't differ from each other by one proton. the conjugate base of HBr is the Br^- ion; the conjugate acid of PO₄^3- is the HPO₄^2- ion.

c. HCN and CN^- represent a conjugate acid-base pair. since they differ from each other by one proton.

d. HF and F^- represent a conjugate acid-base pair.as they differ from each other by one proton.
