1. Calcium fluoride (fluorspar or fluorite) is a partially

soluble ionic compound used in metallurgy, particularly

in aluminum and steel production. When placed in

water, the solid is in equilibrium with its ions.

a. Write a balanced equation to show this

equilibrium.

b. What happens to the position of equilibrium if

soluble calcium chloride is added to the solution

of calcium fluoride?

C. What will happen to the equilibrium concentration

of F- when calcium chloride is added?
