Chapter 16, Problem 59RQ

Interpretation Introduction

Interpretation:

The concentration of $\left[{\text{D}}^{+}\right]$ and the concentration of $\left[{\text{OD}}^{-}\right]$ are to be calculated. The value of $\text{pD}$, $\text{pOD}$ and neutral $\text{pD}$ are to be calculated.

Concept introduction:

The $\text{pOH}$ measures the concentration of hydroxide ions in the solution. It can be expressed as negative logarithm of concentration of hydroxide ions, i.e. pOH = - log [OH^-].

The pH measures the concentration of hydrogen ions in the solution. It can be expressed as negative logarithm of concentration of hydrogen ions, i.e. pH = - log [H⁺].

The solution with a high concentration of hydronium has low $\text{pH}$ value and the solution with low concentration of hydronium ions has high $\text{pH}$ value.

The product of $\left[{\text{H}}^{+}\right]$ and $\left[{\text{OH}}^{-}\right]$ ions concentration is constant at a constant temperature which is called the ionic product of water, K_w.
