Determine the pKa of an acid; a 4e-3M solution of which has a pH of 2.4
The pKa value is ammonia is 9.3. You are allergic to the odor of ammonia. You smelled an ammonia solution with the pH 9.3 yesterday and it was OK. Now you tried to smell the same solution but with the pH of 8.3. What will happen to your allergy symptom? How much better or worse it will be compared to yesterday? (e.g., ~5 times better or worse).
What is the pKb of the conjugate base of a weak acid that has a pKa equal to 5.29 at 25ºC?
