I want to ask what is the product of this reaction:
HF + NaOH -->
I had an arguement with my friends about this problem, some said NaF, other said NaHF₂ and the rest said both

[DevaDevil]

The HF₂^- ion is generally only found in any quantity in concentrated HF (nearing 100 mole-%), by disproportionation of the HF.

so if you have weaker solutions of HF and NaOH in water it is a basic acid-base reaction with water and sodium- and fluoride ions as products.

Also in the gas phase...since the poster didn't mention what phase this reaction was in (probably aqueous though, you're right )
