Chapter 18.3, Problem 36SSC

Interpretation Introduction

Interpretation:

The process of determining $pH$ of a solution knowing its $pOH$ is to be explained.

Concept introduction:

pH gives the concentration of hydrogen ion in a solution.

It tells about acidity and basicity of a solution.

It is given by:

$\begin{array}{l}pH=-\log \left[H^{+}\right]\\ pOH=-\log \left[O{H}^{-}\right]\\ pH+pOH=14\\ \left[H^{+}\right]isconcentationofhydrogenions\\ \left[O{H}^{-}\right]isconcentationofhydroxylions\end{array}$

Answer to Problem 36SSC

Using formula $pH=14-pOH$, $pH$ can be calculated.

Explanation of Solution

The sum of $pH$ and $pOH$ is 14. So knowing the value of $pOH$, value of $pH$ can be calculated.

Conclusion

$pH$ can be calculated by using formula

$pH=14-pOH$
