Interpretation Introduction

Interpretation:

Find the correct concluded of this buffer.

Concept introduction:

A buffer solution contains a weak acid/base mixed with its conjugate base/acid.

pH of the buffer solution is determined by:

$\text{pH}\text{=}{\text{pK}}_{\text{a}}\text{+}\text{log}\frac{\left[\text{salt}\right]}{\left[\text{acid}\right]\text{or}\left[\text{base}\right]}$
