Question

Write the balanced net ionic equation for the reaction of potassium hydroxide and hydrofluoric acid in aqueous solution?

Answer 1

`H_3O^+ + HO^(-) rarr H_2O`

Explanation:

Of course the complete equation is...

`HF(aq) + KOH(aq) rarr KF(aq) + H_2O(l)`

Note that fluoride anion is a weak Bronsted base...

`F^(-)+H_2O(l) rightleftharpoons HF(aq) + HO^-`

We would expect solution of fluoride salts to be WEAKLY basic on this basis....
