Answer 2

1. HF and NaF can be used to prepare a buffer solution.

Explanation:

• A buffer solution is formed by dissolving an acid with their conjugate base (C.B) or by base with their conjugate acid(C.A).
• It helps in maintaining the $pH$ of the solution, and does not let it change on addition of an acid or a base.
• In the given options, HF and NaF will make a buffer solution as HF is a stron acid and NaF is its sodium salt.
• NaF is also the conjugate base of HF.
• Therefore, option 1. HF and NaF is correct.
