Question

Which of the following will increase the percent of HF that is converted to the fluoride ion in water?

(a)

addition of NaOH

Adding hydroxide to the solution will ---Select--- increase, decrease, not affect the hydronium concentration in the solution. According to Le Châtelier's principle, this will ---Select--- increase, decrease, not affect the dissociation of hydrofluoric acid, and the fluoride ion concentration will ---Select--- increase, decrease, not be affected .

(b)

addition of HCl

Adding hydronium to the solution will ---Select--- increase, decrease, not affect the hydronium concentration in the solution. According to Le Châtelier's principle, this will ---Select--- increase, decrease, not affect the dissociation of hydrofluoric acid, and the fluoride ion concentration will ---Select--- increase, decrease, not be affected .

(c)

addition of NaF

Adding fluoride to the solution will ---Select--- increase, decrease, not affect the total fluoride concentration in the solution. According to Le Châtelier's principle, this will ---Select--- increase, decrease, not affect the dissociation of hydrofluoric acid, the hydronium ion concentration will ---Select--- increase, decrease, not be affected , and the fluoride ion concentration derived from hydrofluoric acid will ---Select--- increase, decrease, not be affected .
