Achemist obtains 500.0 ml of a solution containing an unknown concentration of calcium iodide, cai2. he pipets 15 ml of this solution into a 100 ml volumetric flask and dilutes to the mark. he then pipettes 10 ml of this diluted solution into a 25 ml volumetric flask and dilutes to the mark. he analyzes some of the solution from the final volumetric flask and finds that the iodide ion concentration is 0.41 m. (note: in solution, calcium iodide breaks apart into one ca2+ ion for every two i- ions, so a solution that is 1.0 m in cai2 is 2.0 m in determine the molar concentration of calcium iodide in the original solution. latex: cai _{2} (s)→ ca^{ 2+}(aq)+2 i^{-}(aq)
