Chapter 19, Problem 19.127P

(a)

Interpretation Introduction

Interpretation:

Among the given solvents, which solvent should be taken in order to dissolve the maximum amount of $Ca{F}_2\left(K_{sp}=3.2\times {10}^{-11}\right)$ to make $1L$ of aqueous solution has to be determined. 

Concept Introduction:

Effect of a Common ion on solubility:

The addition of a common ion decreases the solubility of a slightly soluble ionic compound. 

Le Chatelier's principle:

Le Chatelier's principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change to reestablish equilibrium.
