Chemistry Question on Law Of Chemical Equilibrium And Equilibrium Constant
What is meant by the conjugate acid-base pair? Find the conjugate acid/base for the following species: HNO2, CN– , HClO4,F–,OH–,CO and S2–
Answer
A conjugate acid-base pair is a pair that differs only by one proton. The conjugate acid base for the given species is mentioned in the table below.
Species Conjugate acid-bas
| Species | Conjugate acid-base |
|---|---|
| HNO2 | NO-2(base) |
| CN- | HCN(acid) |
| HClO4 | ClO4-(base) |
| F- | HF(acid) |
| OH- | H2O(acid) / O2(base) |
| CO32- | HCO3-(acid) |
| S2 | HS(acid) |
