1. Determine the mass of CaCl2:2H2O (MW 147.02 g/mole) to weigh out using a four- place analytical balance to prepare 100 mL of a 0.1005 M solution of Ca2+. 2. Determine the mass of KCI to weigh out using a four-place analytical balance to prepare 100 mL of a 1 M solution of KCI (MW 74.5513 g/mole). 3. Record the solubility of calcium carbonate in water (mg/L) in your notebook. 4. Calculate the amount of calcium carbonate (mg) not in solution if a tablet is dissolved in 250 mL of water and the tablet's label claim is 600 mg calcium / tablet. The source of calcium in the tablet to be analyzed is calcium carbonate (CaCO3). Calcium, as the Ca+2 ion, must be solution to accurately quantitate the (mg calcium / tablet) using an ISE. 5. What could be added to a solution to increase the solubility of CaCO3 in water? 6. Write the net ionic equation for calcium carbonate in acidified water.
