Question

Identify the conjugate acid-base pair for the following reaction in an aqueous solution.

\[\ce{HPO^{2-}_4 + SO^{2-}_3 ⇌ PO^{3-}_4 + HSO^-_3}\]

Answer 1

	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	\[\ce{HSO^{-}_3}\]	\[\ce{SO^{2-}_3}\]	\[\ce{PO^{3-}_4}\]	\[\ce{HPO^{2-}_4}\]
