A chemist dissolves a 1.497-g sample of a type of metal (an alloy of Sn, Pb, Sb, and Cu) in nitric acid, and metastannic acid, H2SnO3, is precipitated. She heats the precipitate to drive off the water, which leaves 0.4909 g of tin(IV) oxide. What was the percentage of [in in the original sample?
A. 1.4639 g sample of limestone was analyzed for Fe, Ca and Mg. The iron was determined as Fe2O3, yielding 0.0357 g Calcium was isolated as CaSO4, yileding a precipitate of 1.4058 g and Mg was isolated as 0. 0627 g of MgP2O7. Report the amount of Febas %w/w Fe2O3, Ca as %w/w CaO and Mg in the limestone sample as % w/w MgO
An ore containing Fe3O4 was analyzed by dissolving a 1.5419-g sample in concentrated HCl. HNO3 was then added to oxidize any Fe2+ to Fe3+. The Fe3+ was precipitated as Fe(OH)3 by adding NH3. The precipitate was collected by filtration and was finally heated yielding 0.8525 g of Fe2O3. Report the concentration of Fe3O4 in the sample as %(w/w). (Note: the final answer is said to be 53.4%)
What iare the reaction equations of the following: (a) 5g of Na2SO3(s) is mixed with 30 ml of distilled water and disolved (b) 6g of CuCl2.H2O(s) is mixed with 20 ml of distilled water and disolved, (c) the solution from (b) is poured into (a) and then then 20ml of 0.001M H2SO4+ is added (d) The CuCl white crystalls are filtered and washed three times with 10ml ethanol and 20ml 0.001M H2SO4+ is added
A 0.4852g sample of an iron ore was dissolved in acid to the 3+ state, then precipitated as Fe2O3 x H2O. The pp was filtered, washed and calcined to Fe2O3, which gave a weight of 0.2481g. Calculate the Fe % in the sample.
A sample of impure KI weighing 0.600 g is dissolved in water, the solution acidified, and 25.00 mL of 0.0400 M KIO3 (an excess ) is added. The iodate is reduced to I2 and the iodide is oxidized to I, The I2 is boiled off, the solution cooled, and an excess of pure KI is added to react with the unused KIO3. The I2 produced is titrated with 40.38 mL of 0.1053 N thiosulfate. Write the equations for the reactions which occurred and calculate the percentage of KI in the sample.
A pure oxide of iron weighing 1.000 g is fused with K2S2O7 and the fused material dissolved in acid. The Fe3+ is reduced with SnCl2, HgCl2 is added, and the Fe2+ titrated with 0.1667 M K2Cr2O7 solution, requiring 12.96 mL. What was the formula of the original oxide?
What is the percentage of Fe in an iron ore of 0.5 g of the ore,after solution, in acid and complete reduction of the iron, requires 25.50 ml KMnO4(1 ml is equivalent to 0.0126 g H2C2O4.2H2O) for oxidation?
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 Chemist collected a 0.4891-g sample of an ore for Fe determination by a redox titration with K2Cr2O7.The ore was carefully crushed prior to weighing and dissolved in HCl and using a Jones reductor the ironin the sample was brought into the +2 oxidation state.
