WebThe pH of a salt solution is determined by the relative strength of its conjugated acid-base pair. Salts can be acidic, neutral, or basic. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride (NH4Cl). Salts that form from a weak acid and a strong base are basic salts, like sodium bicarbonate (NaHCO3). WebJul 10, 2024 · We will discuss the process for preparing a buffer of HF at a pH of 3.0. We can use the Henderson-Hasselbalch approximation to calculate the necessary ratio of F - and HF. (1) p H = p K a + log [ B a s e] [ A c i d] (2) 3.0 = 3.18 + log [ B a s e] [ A c i d] (3) log [ B a s e] [ A c i d] = − 0.18 (4) [ B a s e] [ A c i d] = 10 − 0.18
