Calculate the content of an Iron(II)-solution in (g/l) (under the confidence interval of 95%) at a titration of 50 ml strong acidic solution with KMnO4-solution (0.1 mol/l). Volume used : 24.1 ml , 23.9 ml , 23.8 ml , 24.0 ml.
midpoint: x̄=23.95 ml
standard deviation: s = sqrt( sum(x-x̄)^2 / n-1)= 0.129
s95% = +/- 0.129 * t(95%,3) = +/- 0.129 * 3.18 = +/- 0.41 ml
Volume = 23.95 +/- 0.41 ml
What should be done afterwards?

The iron content of iron ore can be determined by titration with a standard KMnO4 solution....
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...

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....
