- Iron corrodes to produce rust, Fe2O3, but other corrosion products that can form are Fe(O)(OH), iron oxyhydroxide, and magnetite, Fe3O4.It turns out that there are two different kinds of Fe in magnetite that have different oxidation numbers. Suggest what these oxidation numbers are and what their relative stoichiometry must be, assuming oxygen’s oxidation number is -2.What is the oxidation state of the boldfaced element in (a) P2O5, (b) Nah, (c) Cr2O7?what is the oxidation state K in KHSO3
- The blood alcohol (C2H5OH) level can be determined by titrating a sample of blood plasma with an acidic potassium dichromate solution, resulting in the production of Cr3+ (aq) and carbon dioxide. The reaction can be monitored because the dichromate ion (Cr2O72-) is orange in solution, and the Cr3+ ion is green. The balanced equation is 16H+(aq) + 2Cr2O72-(aq) + C2H5OH(aq) -> 4Cr3+(aq) + 2CO2(g) + 11H20. If the blood alcohol limit is 0.08%, what concentration in M of Cr2O72-(aq) would you use , such that titrant volume will be 2.00 mL for a 5.00 mL sample that would be over the limit ?
