1. Describe the difference between the reaction quotient and the equilibrium constant.

2. Give an example of a chemical reaction and the expression that you would use to calculate its Keq.

3. How does the solubility constant relate to the equilibrium constant?

4. List an ionic compound whose dissociation equation has unequal coefficients and write out its Ksp expression.

5. The first step in the preparation of magnesium metal is the precipitation of Mg(OH)2 from sea water by the addition of Ca(OH)2. The concentration of Mg2+(aq) in sea water is 5.37 × 10-2 M. Calculate the [OH-] at which [Mg2+] is diminished to 1.0 × 10-5 M by the addition of Ca(OH)2.

The Ksp for Mg(OH)2 is 7.1 x 10-12
