In the chаpter sectiоn оn аcid/bаse prоperties of salt solutions, you learned that protonated forms of weak bases can act as weak acids. Given that for ammonia, NH3, Kb = 1.8 x 10-5, calculate the pH of a 0.2 M solution of NH4Br. Hint: NH4Br dissociates 100% in water and act as a weak acid (NH4+). This is therefore a weak acid pH calculation with given Kb instead of Ka.
