The amount of iron in ore can be quantitatively determined by titrating a solution of the unknown with a standard solution of dichromate, Cr2O,. The net ionic equation is 6FE2* (aq) + Cr20,2 (aq) + 14H*(aq)→6FE**(aq) + 2Cr (aq) + 7H2O(aq) Part A The titration of 25.0 mL of an iron(II) solution required 18.0 mL of a 0.235 M solution of dichromate to reach the equivalence point. What is the molarity of the iron(11) solution? Express your answer to three significant figures and include the appropriate units. > View Avallable Hint(s)
