Is NaF acidic or basic or neutral?

Answer 1

In the context of the question, it is none of those. It is a salt formed by the neutralization reaction between an acid and a base. In this context, the term neutral refers to an equalibrium point which is neither acid nor base, but the term does not apply to the the salt, which has no Hydrogen ion concentration (pH) to measure.

Answer 2

NaF is a basic salt, as it is the product of a strong base (NaOH) and a weak acid (HF). It hydrolyzes in water to produce a basic solution.
