Question
Identify the conjugate acid-base pair for the following reaction in an aqueous solution.
\[\ce{HPO^{2-}_4 + SO^{2-}_3 ⇌ PO^{3-}_4 + HSO^-_3}\]
Solution
| Acid (Acid1) |
Conjugate base (Base1) |
Base (Base2) |
Conjugate acid (Acid2) |
|
| Forward reaction | \[\ce{HPO^{2-}_4}\] | \[\ce{PO^{3-}_4}\] | \[\ce{SO^{2-}_3}\] | \[\ce{HSO^{-}_3}\] |
| Backward reaction | \[\ce{HSO^{-}_3}\] | \[\ce{SO^{2-}_3}\] | \[\ce{PO^{3-}_4}\] | \[\ce{HPO^{2-}_4}\] |
