You are asked to prepare a pH=3.00 buffer solution starting from 1.25 L of a 1.00M solution of hydrofluoric acid (HF) and an excess of sodium fluoride (NaF).
What is the pH of the hydrofluoric acid solution prior to adding sodium fluoride?
How many grams of sodium fluoride should be added to prepare the buffer solution? Neglect the small volume change that occurs when the sodium fluoride is added.
