Question

When aqueous solutions of sodium fluoride and nitric acid are mixed, an aqueous solution of sodium nitrate and hydrofluoric acid results. Write the net ionic equation for the reaction.

Answer 1

Chemical equation for the reaction between sodium fluoride and nitric acid to form sodium nitrate and hydrofluoric acid can be written as follows. We can derive the net ionic equation for this reaction from its balanced equation.

HF (aq)+NaN (a HNOs (a) Na F (a) L tbreyel

We can write the ionic equation in the solution as follows.

0A90 Ha)NU,a) tNa a)Fa)-

Since HF is relatively weak, it will exist in the solution without any dissociation, so equation will become as follows,

so the net ionic equation for the reaction is

H'aw+ Hia +Nlara3 (a)t F(a) HFaNoa)Nr a) CF HF@D H'aq) +F(ag)

  H⁺ (aq) + F^{​​​​​​-} (aq) ----> HF(aq)
