Chapter 16, Problem 100E

Interpretation Introduction

Interpretation:

The mass of sodium formate that is dissolved to $250{\text{cm}}^3$ of a $1.4\text{M}$ of formic acid to prepare a buffer with $\text{pH}\text{3}\text{.36}$ is to be calculated.

Concept introduction: A buffer solution consists of a specific amount of weak acid and its conjugate base or a specific amount of weak base and its conjugate acid.

Henderson-Hasselbalch equation provides an expression by which the pH of a buffer solution by initial concentrations of the components of the buffer solution can be calculated.

To determine: The mass of sodium formate that is dissolved to $250{\text{cm}}^3$ of a $1.4\text{M}$ of formic acid, to prepare a buffer with $\text{pH}\text{3}\text{.36}$ .
