This laboratory investigates the Ksp of potassium chloride (KCl) and sodium chloride (NaCl). 1. A dropper was calibrated to determine the volume of a drop of water using a graduated 10.0-mL cylinder. The number of drops required to fill a volume of 1.00-mL was recorded.
2. The process was repeated for distilled water twice more and the average of the three values recorded in the data table.
3. Two ice water baths were prepared by crushing enough ice to fill a styrofoam cup and adding enough water to cover the ice.
4. A 50-mL beaker about 3/4 full of distilled water was placed into one ice bath to be used as the solvent during the experiment, and to be as near to 0oC as possible.
5. Into the other ice bath was placed an empty 50-mL beaker to be used as the reaction vessel for the experiment.
1. The entire sample of premassed KCl was placed in the mortar and pestle, the mass recorded, and
