AP Chemistry: Other Aspects of Aqueous Equilibria AP Chemistry Other Equilibria WS 0809.doc Name: ___________________________________ Date: _______________________ Per: _____ 1. Write the solubility product expressions for the following salts: a) AgCl b) Hg 2 Cl 2 c) Pb 3 (AsO 4 ) 2 2. A liter of solution saturated at 25.0 o C with calcium oxalate, CaC 2 O 4 , is evaporated to dryness, giving a 0.0061g residue of CaC 2 O 4 . Calculate the solubility product constant for this salt at 25.0 o C. 3. By experiment, it is found that 1.2x10 -3 mol of lead(II)iodide, PbI 2 , dissolves in 1.00L of aqueous solution at 25.0 o C. What is the solubility product constant at this temperature? 4. Anhydrite is a calcium sulfate mineral deposited when seawater evaporates. What is the solubility of calcium sulfate, in grams per liter if K sp for calcium sulfate is 2.4x10 -5 ? 5. Determine the molar solubility of calcium oxalate in 0.15M calcium chloride? Use the solubility constant determined in question 2 above, and compare the relative solubility of the CaC
