Math with Solubility Equilibria

On Friday, we observed a demonstration of milk of magnesia being combined with HCl.  Complete the following in terms of your observations during the demonstration and understanding of solubility equilibrium:

1. Describe the demonstration performed on Friday.
2. What does the Ksp = 1.8 * 10^-11 tell you about Mg(OH)2?
3. Explain the processes which resulted in the observed color/transparency changes.
4. Did the addition of 1.0M HCl change the Ksp of Mg(OH)2?
5. Calculate the solubility (g/L) of Mg(OH)2 in distilled water.
