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.
The mixture of HF & NaF will act as a buffer solution, because HF is a weak acid and NaF is its conjugate base.
What is buffer solution?
Buffer solutions are those solutions which are made from the combination of weak acid and its conjugate base or of weak base and its conjugate base.
Among HBr, HF, HCl and HI all are strong acids except the HF acid. HF is the weak acid and NaF is its conjugate base, so the combination of HF and NaF will make the buffer solution.
Hence option (b) is correct, i.e. HF, NaF will act as buffer solution.
