Question

Using the conjugate acid-base pairs listed below,complete the following equation with the pair that gives an equilibrium constant K_c > 1. ________ + HSO₃^- ⇌ ________ + H₂SO₃ A)CH₃CO₂H/ CH₃CO₂^- B)HCO₂H/ HCO₂^- C)HNO₂/NO₂^- D)HNO₃/NO₃^-

Quizplus · Accepted Answer

Only the conjugate acid-base pair HNO₃/NO₃ has a Ka (equilibrium constant for the acid dissociation) value greater than 1, which is necessary for the forward reaction to be favored. Both A and B contain the weak acid CO₂, which has a Ka value <1, and C contains the strong acid HNO₂, which does not undergo significant dissociation in water.
