Question

In liquid HF, what is the strongest base allowed? NaOH, HF, H2F+, HF2- ( The answer is HF2-,) Can someone explain why?

In liquid HF, what is the strongest acid allowed? HCl, HF, H2F+, HF2- (Answer is H2F+) Explain why?

In liquid HF how does NaF react? As base, As acid, amphoteric, (Answer is as base) Explain why?

Can someone please explain the steps to getting to these answers.

Explanation / Answer

a) The strongest base is HF2- because it doesnt easily give away the Hydrogen present and it is a weak acid so it is a good Base

b) The strongest acid allowed is HF2- as it will readily give away its H+ and form an ionic bonding with the HF present

c) In liquid HF NaF will react as a base as HF will tend to give away its H+ to the F- of the NaF as it is easily dissociated into ions and the HF will tend be as NaF
