A student prepared a saturated solution of magnesium hydroxide for analysis of the equilibrium of dissolution of this sparingly soluble solid. Titration was used to determine the concentration of hydroxide in solution after filtering the excess solid that persisted in the solution. If 30.0 mL of Mg(OH)2 solution were titrated using 4.83 mL 0.0020 M HCI, what is the value of Ksp for magnesium hydroxide?
A solution containing CaCl2 is mixed with a solution of Li2C204 to form a solution that is 3.5 × 10-4 M in calcium ion and 2.33 × 10-4 M in oxalate ion. What will happen once these solutions are mixed? Ksp (CaC204) = 2.3 × 10-9. A precipitate will form as calcium oxalate is not soluble to any extent. A precipitate will form since Q > Ksp for calcium oxalate. Nothing will happen since both calcium chloride and lithium oxalate are soluble compounds. Nothing will happen Ksp > Q for all possible precipitants. There is not enough information to determine.
The solubility product constant for CaCO3 (s) in water is Ksp = [Ca+2] [CO3 -2] = 4.8 x 10^-9 Consider a 1.00 M solution of calcium chloride, in which you drop a piece of Dry Ice. Show that the minimum concentration (threshold amount) of carbonate ions necessary for a precipitate to appear is 4.8 x 10-9 M. Another way to think about this situation is to calculate the Q for the calcium chloride/Dry Ice solution and ask “will precipitation occur?”..
