- A slag sample is known to contain all of its iron in the forms of FeO and Fe2O3. A sample of 1,000 g of the slag was dissolved in hydrochloric acid according to the usual method, then reduced with stannous chloride and finally titrated with a 0.02237 M solution of potassium permanganate, of which 28.59 mL were used. A second aliquot of the slag sample, weighing 1,500, was dissolved in a nitrogen atmosphere to further adjust the oxidation state of the iron, it was immediately titrated with the same potassium permanganate solution. If this second experiment required 15.60 mL of permanganate solution, calculate: a) The percentage of total iron in the slag. b) The percentages of the oxide FeO and Fe2O3arrow_forwardWhat is the oxidation state of tungsten in WO3?arrow_forwardTreatment of cobalt(II) oxide with oxygen at high temperatures gives Co3O4.

- Sodium hydrogen sulfate is used as a cleaning agent and as a flux (a substancethat promotes the fusing of metals and prevents the formation of oxides). Oneof the ways in which sodium hydrogen sulfate is manufactured is by reactingsodium dichromate, Na2Cr2O7, with sulfuric acid. This process also forms waterand chromium(VI) oxide, CrO3.a. Write a balanced equation for this reaction. (You do not need to includestates.)b. How many kilograms of sodium dichromate, Na2Cr2O7, are necessary toproduce 130.4 kg of sodium hydrogen sulfate?c.
