A solution of sodium thiosulfate was standardized by dissolving 0.1172 g KIO3 (214.00 g/mol) in water, adding a large excess of KI, and acidifying with HCI. The liberated iodine required 44.09 mL of the thiosulfate solution to decolorize the blue starch/iodine complex. Calculate the molar concentration of the Na2S2O3.

What is the full equation (not the net ionic equation) for the chemical reaction of 0.001 M Fe(NO3)3 plus 0.0002 M NaSCN diluted up to 10 mL with 0.1M HNO3? Please include the acid that is the diluent.
A mixture of solid chlorides was known to contain some or all of the following cations: Ag ,Al^3+Cr^3+,Ca^2+,and/or Zn^2+ . A student performed the following steps: 1.Water was added to the solid and the mixture was stirred well. After several minutes, some of the solid did not dissolve. The mixture was centrifuged and the supernatant was decanted from the solid (solution A). 2. NH4CI(aq) was added to solution A followed by NH3(aq) until the solution was basic to litmus. A gray-green precipitate was formed. The mixture was centrifuged and the supernatant (solution B) was decanted. The solid dissolved in NaOH(aq) and H2O2(aq) to form a light yellow solution. The solution was heated to dryness to remove the H2O2 and the solid was redissolved in HCI(aq). When ammonia was added to make the solution basic, a light yellow solution formed and no solid precipitated. 3. (NH4)2C204(aq) was added to solution B, and a precipitate formed. The mixture was centrifuged and the supernatant (solution C)…
A 0.6883 gram sample of impure potassium chlorate was treated with 45.00 mL of 0.1020 M Fe(NH4)2(SO4)2. The reaction is: ClO3-+6Fe2++6H+->Cl-+6Fe3++3H2O When the reaction was complete, the excess Fe(II) was back-titrated with 9.004 mL of 0.01734 M K2Cr2O7. Cr2O7-+6Fe2++14H+->2Cr3++6Fe3++7H2O Calculate the percent KClO3 (FW = 122.55) in the sample.
A quantitative analysis for ethanol, C2H60, is accomplished by a redox back titration. Ethanol is oxidized to acetic acid, C2H402, using excess dichromate, 3+ Cr207 2-, which is reduced to Cr3*. The excess dichromate is titrated with Fe2*, giving C and Fe+ as products. In a typical analysis, a 5.00-mL sample of a brandy is diluted to 500 mL in a volumetric flask. A 10.00-mL sample is taken and the ethanol is removed by distillation and collected in 50.00 mL of an 2- acidified solution of 0.0200 M K2Cr207. Titration of the unreacted Cr207 requires 21.48 mL of 0.1014 M Fe2*. Calculate the %w/v ethanol in the brandy. Which is the titrant in this problem? C2H402 Fe2+ C2H60 O Cr207 2-
If 3.00g ruthenium (III) chloride, RuCl3 is added to 75.0mL of a 3.00M sodium periodate, NaIO4 solution. What is the mass of RuO4 produced by the reaction? 8RuCl3+5NaIO4+12H2O=8RuO4+5NaI+24HCl.What is the reducing agent and what is the oxidizing agent?
0.7120 g of iron ore was dissolved and the iron was reduced to Fe2+ with Jones's reagent. Fe(II) was titrated with 0.02086 M KMnO4 and consumed 39.21 mL. What is the iron content of iron ore? Report the concentration as percentage of iron (Fe%) and iron oxide (Fe2O3%).
Twenty tablets of an iron food supplement whose total mass was 22.131 g were crushed and perfectly mixed. Then 2.998g of the powder was dissolved in HNO3 and the solution was heated to convert all the iron to Fe+3. By addition of NH3 it was quantitatively precipitated as Fe(OH)3•H20 which was calcined to form 0.264g of Fe203. Calculate the Fe content in each tablet.
A 25.00-mL sample of a household cleaning solution was diluted to 250.0 mL in a volumetric flask. A 50.00-mL aliquot of this solution required 41.27 mL of 0.1943 M HCI to reach a bromocresol green end point. Calculate the mass/volume percentage of NH3 in the sample. (Assume that all the alkalinity results from the ammonia.)
Q7/ A 0.8040-g sample of an iron ore was dissolved in acid. The iron was then reduced to Fe* and titrated with 47.22 mL of 0.1121 N (0.02242 M) KMnO, solution. Calculate the results of this analysis in terms of (a) percent Fe (55.847 g/mol) und (b) percent Fe;O4 (231.54 g/mol). The reaction of the analyte with the reagent is described by the equation MnOj; + 5Fe®* + SH* — Mn?* + 5Fe’* + 4H,0
The formaldehyde content of a pesticide was determined by weighing 0.9327 g of the liquid sample into a flask containing 50.0 mL of 0.08624 M NaOH and 50 mL of 3% H2O2. It was heated then cooled. After cooling, the excess base was titrated with 27.8 mL of 0.06325 M H2SO4. Calculate the percentage of HCHO in the sample.
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%)
Na2S2O3 was standardized using primary standard KIO3. A 0.1000 g sample of KIO3 (FW=214.00 g/mol) was dissolved in dilute HCl. 25.00 mL of water was added with an unmeasured excess of KI. The liberated iodine required 18.50 mL of Na2S2O3. What is the molar concentration of the titrant?
