A chemist obtains 500.0 mL of a solution containing an unknown concentration of calcium iodide (CaI 2). She pipets 25 mL of this solution into a 100 mL volumetric flask and dilutes to the mark. Shethen pipets 10 mL of this diluted solution into a 25 mL volumetric flask and dilutes to the mark. She analyzes some of the solution from the final volumetric flask and finds that the iodide ion concentration is 0.00000446 M. (in solution, calcium iodide breaks...
