Chapter 14, Problem 78E

Interpretation Introduction

Interpretation:

For each of the given solution, the pH is to be determined with the help of strong acids and base concentration.

Concept Introduction:

The pH of the solution is defined as the negative logarithm of hydrogen ion concentration $\left[{\text{H}}_{\text{3}}{\text{O}}^{+}\right]$ and mathematically, written as follows:

$\text{pH}=-\log \left[{\text{H}}_{\text{3}}{\text{O}}^{+}\right]$ …… (1)

Similarly, the pOH of the solution is defined as the negative logarithm of $\left[{\text{OH}}^{-}\right]$.

Mathematically, it is written as follows:

$\text{pOH}=-\log \left[{\text{OH}}^{-}\right]$ …… (2)

The sum of pH and pOH in a solution is always equaled to $14$ at a constant temperature and it can be shown mathematically as follows:

$\text{pH}+\text{pOH}=\text{14}\text{.00}$ …… (3)

The complete ionization of strong acids and bases occurs in the solution and their ionization is indicated by the single arrow pointing to the right in the reaction equation.
