Chapter 18, Problem 89FP

The accompanying drawing suggests a series of manipulations starting with saturated Mg(OH)₂(aq) Calculate $\left[{\text{Mg}}^{\text{2+}}\left(\text{aq}\right)\right]$ at each of the lettered stages

1. 0.500 L of saturated $\text{Mg}{\left(\text{OH}\right)}_2\left(\text{aq}\right)$ is in contact with $\text{Mg}{\left(\text{OH}\right)}_2\left(\text{s}\right)$ .
2. 0.500 L of H₂O is added to the 0 500 L of solution in part (a), and the solution is vigorously stirred Undissolved $\text{Mg}{\left(\text{OH}\right)}_2\left(\text{s}\right)$ remains.
3. 100 0 mL of the clear solution in part (b) is removed and added to 0 500 L of 0.100 M HCl(aq).
4. 6 25 00 mL of the clear solution in part (b) is removed and added to 250.0 mL of 0 065 M $\text{Mg}{\left(\text{OH}\right)}_2\left(\text{aq}\right)$ .
5. 50.00 mL of the clear solution in part (b) is removed and added to 150 0 mL of 0 150 M KOH(aq)
