Question
When ammonium (NH4+) is placed in water, a
NH4+ (aq) + H2O (l) ⇄ NH3 (aq) + H3O+ (aq)
The pKa of NH4+ is 9.25. Predict whether the acid form (NH4+) or the base form (NH3) is predominant at pH = 7.4.
Expert Solution

Step 1
Answer:
NH4+ ion which is a weak acid when added into the water, its hydrolysis would take place and that will generate H3O+ ions and NH3 in the solution and soon an equilibrium between these species will be established.
