Question

When ammonium (NH4+) is placed in water, a chemical reaction occurs and an equilibrium is established as shown below. 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. Explain your answer.

Step 1

The pKa value tells us about the acidity of a substance: the lower the pKa, the stronger the acid. In this case, the pKa of NH4+ is 9.25. This means that NH4+ is a weak acid, as it has a relatively high pKa value. Show more…

Ammonium (NH4+) is a weak acid with a pKa of 9.26. The dissociation is: NH4+ → NH3 + H+. Calculate the mass of ammonium added to 1 L of water in order to obtain a pH of 4 at equilibrium.

Ammonia (NH3) ionizes according to the following reaction: NH3(aq) + H2O(l) ⇌ NH4+(aq) + OH−(aq) The base dissociation constant for ammonia (NH3) is Kb = 1.8 × 10−5. Ammonia (NH3) also has a chloride salt, ammonium chloride (NH4Cl), which is soluble in water. If 0.070 M of ammonia (NH3) and 0.035 M of its salt ammonium chloride (NH4Cl) are mixed in a solution, what is the pH of this solution? 9.6 4.4 1.3 12.7
