The equation for the reaction between hydrofluoric acid (HF) and sodium hydroxide (NaOH) is:

HF (aq) + NaOH (aq) → NaF (aq) + H₂O (l)

Here's what the equation represents:

* HF (aq): Hydrofluoric acid in an aqueous solution (dissolved in water).

* NaOH (aq): Sodium hydroxide in an aqueous solution.

* NaF (aq): Sodium fluoride, the salt formed from the reaction, also in an aqueous solution.

* H₂O (l): Water, a liquid byproduct of the reaction.

This reaction is a classic acid-base neutralization reaction. The strong base (NaOH) reacts with the weak acid (HF) to form a salt (NaF) and water (H₂O).
