Question

Which of the following mixtures may be act as a buffer solution?

Answer 1

Answer:

B) HF, NaF

Explanation:

• A buffer solution is made up of a weak acid and its conjugate base.
• In this case, HF is a weak acid and NaF is the conjugate base, therefore the mixture of HF,  and NaF would make a perfect buffer solution.
• The buffer would have the weak acid HF and its conjugate base, F- which comes from the soluble salt NaF.
