MCQ
Conjugate acid of $HPO_4^{-2}$ is
- A$H_3PO_4$
- ✓${H_2}PO_4^\Theta $
- C$PO_4^{ - 3}$
- D${H_2}PO_3^\Theta $
✓
Answer
Correct option: B.
${H_2}PO_4^\Theta $
b
The conjugate acid of $HPO _4^{2-}$ is $H _2 PO _4^{-}$
The conjugate acid of $HPO _4^{2-}$ is $H _2 PO _4^{-}$
$H _2 PO _4^{-} \rightarrow H ^{+}+ HPO _4^{2-}$
The base and its conjugate acid differ by one proton only.
