Question

What is meant by the conjugate acid-base pair? Find the conjugate acid/base for the following species: HNO2, CN–, HClO4, F –, OH–, CO32- , and S2–

What will be the conjugate bases for the Brönsted acids: HF, H2SO4 and HCO3–?

The species: H2O, HCO3–, HSO4– and NH3 can act both as Brönsted acids and bases. For each case give the corresponding conjugate acid and base.
