WebJan 17, 2024 · A buffer is a solution of a weak acid and its salt (a weak acid and its conjugate base), or a weak base and its salt (a weak base and its conjugate acid). Buffers are solutions that can preserve their original pH when mixed with an acid or base. The ability of the buffer to maintain its pH is called its buffer capacity. WebJan 30, 2024 · To clarify this effect, we can consider the simple example of a Hydrofluoric Acid (HF) and Sodium Fluoride (NaF) buffer. Hydrofluoric acid is a weak acid due to the strong attraction between the relatively small F - ion and solvated protons (H 3 O + ), … Lawrence Joseph Henderson and Karl Albert Hasselbalch.

Buffers … WebJun 16, 2024 · Improve this question. Find the pH value of HF. p H = − log [ H +] for strong acids. p O H = − log [ O H −] for strong bases. p H = 1 / 2 ( p K a − log C) for weak acid. p O H = 1 / 2 ( p K b − log C) for weak base. HF is weak acid so K a = 6.6 × 10 − 4. p H = 1 / 2 ( − log ( 6.6 × 10 − 4) − log ( 0.04)) p H = 2.2892.
