Question

Given that HSO4- is a stronger acid than HPO4^2-, what is the chemical reaction if solutions containing these ions are mixed together? (Hints: One of these must act as an acid and the other as a base. Use the Brønsted-Lowry definition)

Please explain how to get the answer. Thank you!

Answer 1

The hint is supposed to tell you what to do. Since HSO4^- is the stronger acid, it will be the donor and the other will be the acceptor.
HSO4^- + HPO4^2- ==>SO4^2- + H2PO4^-
