Chapter 6, Problem 6G.4BST

Interpretation Introduction

Interpretation:

The ratio of the molar concentrations of benzoate ions and benzoic acid needed to buffer a solution at $pH$ of $3.50$ has to be calculated.

Concept Introduction:

Henderson – Hasselbalch equation:

The $pH$ of a buffer can be easily calculated by using Henderson – Hasselbalch equation as given below.

  $pH=p{K}_a+\log \frac{{\left[base\right]}_{initial}}{{\left[acid\right]}_{initial}}$
