Question

This solution contains equal concentrations of both hf(aq) and naf(aq). write the proton transfer equilibrium (net ionic) reaction that includes f– as a reactant. include states of matter.

Answer 1

In a reaction of NaF and H₂O, NaOH and HF is produced.

The reaction can be shown as follows:

HF(aq.) + OH⁻(aq.) ----->F⁻(aq.) + H₂O(l)

Or it can be shown as below:

Here the reactants are: NaF, H₂O

While the product is: NaOH, HF

So the reaction in ionic can be shown as:

HF(aq.) + OH⁻(aq.) ----->F⁻(aq.) + H₂O(l)

So the reaction can be that includes the states of matter too can be:

HF(aq.) + OH⁻(aq.) ----->F⁻(aq.) + H₂O(l)

Answer 2

Net ionic reaction for the solution containing equal concentrations of both HF(aq) and NaF(aq) is as follow:
F⁻(aq) + H₂O(l) ⇄ HF(aq) + OH⁻(aq)
