tab caps lock You have a 11.5 mg sample of blood that contains various proteins. Hemoglobin is the only protein in the sample containing Fe. Hemoglobin contains 3.83% by mass of a compound called heme (C34H32FeN4O4, MW = 616.49 g/mol). You find that your 11.5 mg blood sample contains 29.7 micrograms of Fe.

The iodine solution is usually made in the presence of iodide ion, forming the more stable triiodide ion, Is, giving the following overall reaction CeHsOc(aq) + Is (aq) + H₂O(1)→ CHO(aq) + 31-(aq) + 2H+(aq) The titration is carried out in the presence of starch, which forms a dark blue complex with the excess iodine when the endpoint is reached. Ascorbic acid can be used to standardize the iodine solution. A 0.315 g sample of ascorbic acid was titrated with iodine solution, requiring 30.2 mL to reach the endpoint.
