Chapter 16, Problem 75RQ

Interpretation Introduction

Interpretation:

The ${\text{K}}_{\text{b}}$ value for ${\text{F}}^{-}$ is to be calculated.

Concept introduction:

$\text{pH}$ measures the concentration of the hydrogen or hydronium ions in the solution.

A solution with a high concentration of hydronium ions has a low $\text{pH}$ value while a solution with a low concentration of hydronium ions has a high $\text{pH}$ value.

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

The acid dissociation constant ${\text{K}}_{\text{a}}$ measures the strength of the acid.
