Chapter 16, Problem 16.133CP

Interpretation Introduction

Interpretation:

Whether the precipitation takes place or not for $\text{5 }\times \text{ 1}{0}^{-\text{4}}\text{M}$ calcium fluoride should be identified.

Concept introduction:
The ionic product of calcium fluoride can be shown as:

  $\text{Ip }=\left[{\text{Ca}}^{\text{2+}}\right]{\left[{\text{F}}^{\text{-}}\right]}^{\text{2}}$

where, $\left[{\text{Ca}}^{\text{2}+}\right]$ is the concentration of calcium ion

  $\left[{\text{F}}^{-}\right]$ is the concentration of fluoride ion
