Determination of Manganese in Steel Odinity

2014-4-17  The weight percentage of Mn in the unknown steel sample was calculated as .51% with 95% confidence interval of 0.71 from the visual spectroscopy method. The absorption of the blank sample containing no standard Mn or KIO 4 was measured to be 0.0395. The measurement of the second sample yielded absorption value of 0.4020.

2014-7-3  Magnesium oxide has formula MgO (that is, #Mg_1O_1#). This means that in every sample of this substance there is the same number of Oxygen and Magnesium atoms.. From the periodic table we see that the atomic masses are 24.3 (Mg) and 16.0 (O). Magnesium atoms are heavier than oxygen atoms, so we expect more than 50% of magnesium in the weight composition.

Solved: A 0.450−g Sample Of Steel Contains

A 0.450−g sample of steel contains manganese as an impurity. The sample is dissolved in acidic solution and the manganese is oxidized to the permanganate ion MnO4−. The MnO4− ion is reduced to Mn2+ by reacting with 50 mL of 0.0800 M FeSO4 solution. The excess Fe2+ ions are then oxidized to Fe3+ by 22.1 mL of 0.0100 M K2Cr2O7. Calculate
