Chapter 9, Problem 9.3P

Interpretation Introduction

Interpretation:

The $\text{pH}$ of $\text{5}{\text{.0×10}}^{\text{-8}}\text{M}{\text{HClO}}_{\text{4}}$ and fraction of ${\text{H}}^{\text{+}}$ derived from dissociation of Water has to be calculated.

Concept Introduction:

The $\text{pH}$ of solution can be calculated as,

$\begin{array}{l}{\text{pH=-logA}}_{{\text{H}}^{\text{+}}}\\ \\ \text{pH=-log}{\left[{\text{H}}^{\text{+}}\right]}_{{\text{γH}}^{\text{+}}}\end{array}$

With the above equation, the negative logarithm of activity of Hydrogen ion can be measured.

To calculate the $\text{pH}$ of $\text{5}{\text{.0×10}}^{\text{-8}}\text{M}{\text{HClO}}_{\text{4}}$ and fraction of ${\text{H}}^{\text{+}}$ derived from dissociation of Water
