Conjugate acid and conjugate base of \(\mathrm{HCO}_3^{-}\)are respectively
- A \(\mathrm{H}_2 \mathrm{CO}_3, \mathrm{H}_3 \mathrm{CO}_3^{+}\)
- B \(\mathrm{H}_2 \mathrm{CO}_3, \mathrm{CO}_3^{2-}\)
- C \(\mathrm{CO}_3^{2-}, \mathrm{H}_2 \mathrm{CO}_3\)
- D \(\mathrm{CO}_3^{2-}, \mathrm{CO}_2\)
Answer & Solution
Correct Answer
(B) \(\mathrm{H}_2 \mathrm{CO}_3, \mathrm{CO}_3^{2-}\)
Step-by-step Solution
Detailed explanation
Conjugate acid of \(\mathrm{HCO}_3^{-}=\mathrm{H}_2 \mathrm{CO}_3\) (has an extra \(\mathrm{H}^{+}\)) Conjugate base of \(\mathrm{HCO}_3^{-}=\mathrm{CO}_3^{2-}\) (has an less \(\mathrm{H}^{+}\))
