Question

What change will be caused by addition of a small amount of HC1 to a solution containing fluoride ions and hydrogen fluoride? The concentration of hydroxide ions will increase significantly. The concentration of fluoride ions will increase as will the concentration of hydronium ions. The concentration of hydrogen fluoride will decrease and the concentration of fluoride ions will increase. The concentration of fluoride ion will decrease and the concentration of hydrogen fluoride will increase. The fluoride ions will precipitate out of solution as its acid salt.

Explanation / Answer

HF + NaF <==> H+ + Na+ + 2F-

If you add HCl to a buffer solution of HF/NaF, the F- will react with H+ to produce HF

Ans : option D) The concentration of fluoride ion will decrease and the concentration of HF will increase.
