Question:
Which of the following is the \(K_b\) for the conjugate base of carbonic acid?
Which of the following is the \(K_b\) for the conjugate base of carbonic acid?
Show Hint
For acid-base equilibria, the conjugate base dissociation constant \(K_b\) is related to the equilibrium concentration of the conjugate base.

- \( \dfrac{[H_2CO_3][OH^-]}{[HCO_3^-]} \)
- \( \dfrac{[H_2CO_3]}{[HCO_3^-][OH^-]} \)
- \( \dfrac{[HCO_3^-]}{[H_2CO_3][OH^-]} \)
- \( [HCO_3^-] \)
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The \(K_b\) for the conjugate base of carbonic acid is the equilibrium constant for the base dissociation of bicarbonate ions, which is given by the expression for the concentration of \( [HCO_3^-] \).
