WebThe conjugate base of a strong acid is a very weak base. Salts formed from those conjugate bases often have a pH of 7, or just above 7. For example, sodium chloride, sodium sulfate, and sodium nitrate all have anions that are conjugate bases of strong acids. All of those salts have a pH near 7 in solution – which is a neutral pH. Strong Bases WebDec 1, 2005 · Hydrofluoric acid (HF) is chemically classified as a weak acid due to its limited ionic dissociation in H 2 O at 25°C [26].

WebIt's even easier to moles the base over the mold of acid. P. H will be equal to P. K. A. There will be a negative log of the K.A. The value for Hydrofluoric acid is 10 to the -4. We'll get P. K. A. if we take the negative log. The log of the base will be added. The base is a substance called fluoride. That's the conjugate base to hydrofluoric acid.
