Calculating Solubility Example: It is found that 1 L of saturated AgBrO3(aq) contains 1.96 g of AgBrO3. What is the molar solubility of AgBrO3? Now you try: The molar solubility of PbI2 is 1.37x10-3 M. Express this value in g/L. Once more: It is found that 250 mL of saturated CaCl2 contains 18.6 g of CaCl2. What is the molar solubility of CaCl2? 25 min

Calculating Ion Concentrations Example 1: What is the concentration of all the ions present in a saturated solution of Ag2CO3 having a concentration of 1.2x10-4 M? Example 2: If 5.0 mL of 0.020 M CuCl2 is added to 15.0 mL of 0.012 M CuBr2, what is the molarity of each ion in the mixture? Write chemical equation and use stoichiometric ratios to solve. – 5 min M1V1=M2V2 – 5 min
