The weak base neutralizes added acid 1.0 L solution pH 0.1 M NH 4 Br 5.13 After adding 0.02 mol NaOH 8.65 After adding 0.02 mol HCl 1.7 1.0 L solution pH 0.1 M NH 4 Br/ 0.1 M NH 3 9.26 After adding 0.02 mol NaOH 9.43 After adding 0.02 mol HCl 9.08 pH = p K a + log [base] [acid] Buffer Solutions Two factor affect the efficiency of a buffer to resist pH changes: 1. Concentrations of the acid and base conjugate pair The greater the concentrations of the buffer components, the greater its capacity to resist pH changes. 2. Relative concentrations of the acid and base The closer the component concentrations are to each other, the greater the buffer capacity.
