A 0.5145-g sample of a water-soluble fertilizer was dissolved and analyzed for nitrogen using the Kjeldahl method. After digestion, the distilled ammonia was collected in 100 mL of 0.1334 M boric acid. This solution required 29.38 mL of 0.202 M HCl for titration to the methyl red end point. Calculate the % N (AW =14 g/mol) in the fertilizer. Type the numerical answer only.
The protein in a 0.2976 -g sample of cheese is determined by the Kjeldahl method. The sample is digested with H2SO4, the resulting solution made basic with NaOH, and the ammonia distilled into 50.00 mL of 0.09756 M HCl. The excess HCl is then back titrated using 39.87 mL of 0.05345 M NaOH. Calculate the % N and % protein of the sample.

A sample consisting of Na2CO3 (105.96), NaOH (39.99) and inert matter weighs 1.179 g. It is titrated with 0.300 N HCI with phenolphthalein as the indicator, and the solution becomes colorless after the addition of 48.16 ml. Methyl orange is then added and 24.08 ml more of the acid are needed for the color change. What is the percentage of NaOH and N22CO3? *
The hydrogen sulfide in a 75.0-g sample of crude petroleum was removed by distillation and uncollected in a solution of CdCl2. The precipitated CdS was then filtered, washed, and ignited to CdSO4. Calculate the percentage of H₂S in the sample if 0.115 g of CdSO4 was recovered.
A sample of unknown iron ore weighs 0.35 g. It is digested using dilute HCl. An SnCl2 solution is added to turn the solution yellow. Zimmermann–Reinhardt reagent is added, and the solution is diluted to 150mL. It is then titrated with 31.30 mL of 0.045 M potassium permanganate. a) How many moles of MnO4- were used to titrate the iron in the sample? b) How many moles of Fe2+ were in the sample? c) What is the mass of iron in the sample? d) What is the % w/w of Fe in the sample?
The reaction of hydroxylamine and Fe(III) produces nitrous oxide, Fe(II) and water: 2H2NOH + 4Fe3+  N2O(g) + 4Fe2+ + 4H+ + H2O. A 50 ml sample of hydroxylamine was treated with Fe(III) solution and the released Fe(II) was titrated with 0.0325 M K2Cr2O7 solution, which consumed 19.83 ml. Calculate the hydroxylamine concentration of the sample.
A solid sample containing some Fe2+ion had a total mass of .9791 g. It required 18.2 ml of 0.02304 M KMnO4 to titrate the Fe2+ in the dissolved sample to a pink endpoint. How many moles of Fe2+ were in the the sample? How many grams of irion were present in the sample and what was the mass percent iron in the sample?
2Fe(s) + 3Cu2+(aq) 2Fe3+(aq) + 3Cu(s) a)Calculate the minimum volume of 1.16M CuSO4 solution that is required to ensure complete reaction of 1.04g of Fe.Since you do not know which reaction will be the one to occur, you must base the calculation on whichever of the equations requires more CuSO4 solution. b)To ensure that sufficient CuSO4 is used, it is common practice to add an excess.Calculate the volume of 1.16M CuSO4 needed to provide a 20% excess in this case.
A solution of malonic acid (H2C3H2O4) with a known concentration of 0.500 M H2C3H2O4 is tirated with a 0.255 M KOH solution.
