Question
Ka values for HA, HB and HD are 10-5, 10-7 and 10-9 respectively. Which of the following will be correct for decimolar aqueous solutions of NaA, NaB and NaD at 25oC?
Options
A.(pH)NaA < (pH)NaB
B.(pH)NaD < (pH)NaB
C.(pH)NaA < (pH)NaD
D.(pH)NaB = 7
Solution
As Ka of acid increases, Kb of its conjugate base decreases.
