The iron content of iron ore can be determined by titration with a standard KMnO4 solution. The iron ore is dissolved in HCl, and all the iron is reduced to Fe2+ ions. This solution is then titrated with KMnO4 solution, producing Fe3+ and Mn2+ ions in acidic solution. If it required 29.83 mL of 0.0447 M KMnO4 to titrate a solution made from 1.128 g of iron ore, what is the mass percent of iron in the iron ore? Mass...

Geologists can estimate the age of rocks by their uranium-238 content. The uranium is incorporated in the rock as it hardens and then decays with first-order kinetics and a half-life of 4.5 billion years. A rock is found to contain 82.4% of the amount of uranium-238 that it contained when it was formed. (The amount that the rock contained when it was formed can be deduced from the presence of the decay products of U−238.) How old is the rock?

Iron tablets may be used in the treatment of anaemia. To analyse the iron(II) content of commercially available iron tablets, a student used four tablets, each of mass 0.360 g to make up 250 mL of solution in a volumetric flask using dilute sulfuric acid and deionized water. About 15.0 mL of dilute sulfuric acid was added to a 25.0 mL portion of this iron(II) solution and the mixture then titrated with a 0.01025 M solution of potassium manganite(VII), KMnO4....
