WitrynaIs there a buffer solution made up of NaF and NaOH? (D) HF and NaOH (D) If you have half as much NaOH as HF, this will act as a buffer. You form F-, the conjugate base … WitrynaSimilarly, NaF is basic (it is the salt of a strong base, NaOH, and a weak acid, HF). NaCl is neutral. This means that two of the solutions are basic (NH3 and NaF), one solution is neutral (NaCl), and the other is acidic (NH4Br). Is NaF a weak or strong base? Similarly, NaF is basic (it is the salt of a strong base, NaOH, and a weak acid, HF).

Witryna18 lip 2016 · Hydrofluoric acid, HF, a weak acid, will react with sodium hydroxide, NaOH, a strong base, to produce aqueous sodium fluoride, NaF, and water. HF(aq) + NaOH(aq) → NaF(aq) +H2O(l) Now, the important thing to remember here is that hydrofluoric acid is a weak acid, which implies that it does not dissociate completely in aqueous solution …
