Chapter 16.3, Problem 3PE

Interpretation Introduction

Interpretation: A weak acid which when mixed with the sodium salt of its conjugate base in approximately equimolar proportions, produces a buffer with a $\text{pH}$ of $1.75$ is to be selected from the given table.

Concept introduction: The potential of ${\text{H}}^{\text{+}}$ ions is called as $\text{pH}$ and the potential of ${\text{OH}}^{-}$ ions is called as $\text{pOH}$. The value of $\text{pH}$ is less than $7$ for acidic solutions and greater than $7$ for basic solutions. For neutral solution the value of $\text{pH}$ is $7$.

To determine: A weak acid which when mixed with the sodium salt of its conjugate base in approximately equimolar proportions, produces a buffer with a $\text{pH}$ of $1.75$ by using a given table.
