Which of the following mixtures may be act as a buffer solution?View Available Hint(s)Which of the following mixtures may be act as a buffer solution?HF, NaFHBr, NaBrHCl, NaClHI, NaI

Answer 1

HF, NaF

Step-by-step explanation:

A buffer system may be formed in one of the following ways:

• A weak acid and its conjugate base.

• A weak base and its conjugate acid.

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

• HF, NaF. YES. HF is a weak acid and F⁻ (from NaF) is its conjugate base.

• HBr, NaBr. NO. HBr is a strong acid.

• HCl, NaCl. NO. HCl is a strong acid.

• HI, NaI. NO. HI is a strong acid.
