1. For the reaction: PbCl2(s) ↔ Pb2+(aq)+2Cl1-(aq), what is Q* when 8.0 mL of 0.054 M lead nitrate is added to 21 mL of 0.025 M sodium chloride?
Ksp of lead chloride is 1.6 x 10-5 M3.
*Recall: Q is compared to Ksp to determine whether a precipitate forms.
2.Sodium phosphate is added to a solution that contains 0.0088 M aluminum nitrate and 0.046 M calcium chloride. The concentration of the first ion to precipitate (either Al3+ or Ca2+) decreases as its precipitate forms. What is the concentration of this ion when the second ion begins to precipitate?
