- Potassium dichromate has several industrial applications. To determine the purity of the salt that will be used in different industrial processes, a sample mass equal to 2.660 g was dissolved and quantitatively transferred to a 500.00 mL flask. An aliquot of 25.00 mL of this solution was treated with excess KI and the released iodine was titrated with 0.1000 mol L-1 sodium thiosulfate, spending 27.00 mL. Calculate the purity of the analyzed salt. Data:K = 39.10 O = 16.00 Cr = 52.00 I = 126.9 S = 32.07For the reduction 2FeCl3 + SnCl2 =====➔ 2 FeCl2 + SnCl4 in aqueous solution the following data were obtained at 25oC t(min) 1 3 7 11 40 Y 0.01434 0.02664 0.03612 0.04102 0.05058 Where y is the amount of FeCl3 reacted in moles per liter. The initial concentrations of SnCl3 and FeCl3 were respectively, 0.03125, 0.0625 moles/L. a.)Show that the reaction is third order (derive the rate law), and b.) calculate the average specific rate constant.The efficiency of a particular catalyst is highly dependent on its zirconium content. The starting material for this preparation is received in batches that assay between 68% and 84% ZrCl4. Routine analysis based on precipitation of AgCl is feasible, if having been established that there are no sources of chloride ion other than the ZrCl4 in the sample. (a) What sample mass should be taken to ensure an AgCl precipitate that weighs at least 0.400g? (b) If this sample mass is used, what is the maximum mass of AgCl that can be expected in this analysis? (c) To simplify calculations, what sample mass should be taken to have the percentage of ZrCl4 exceed the mass of AgCl produced by a factor of 100?
- 8.00mL aqueous suspension of elemental selenium is treated with 24.00mL ammonia 0.045M AgNO3 The reaction is as follows: 6Ag (NH3) 2 ++ 3Se (s) + 3H2O → 2Ag2Se (s) + Ag2SeO3 (s) + 6NH4 + After this reaction is completed, nitric acid is added to dissolve Ag2SeO3. However, Ag2Se does not dissolve during this time. Ag + consisting of dissolved Ag2SeO3 and the excess of the reagent requires 13.43mL 0.01294M KSCN in a Volhard titration. How many milligrams of Se are in each milliliter of sample? (Se = 78.96g / mol)If the influent concentration of contaminant X is 0.064 mg/L, then what dose (mg/L) of powdered activated carbon is required to provide an effluent concentration of 0.002 mg/L. It is a freundlich isotherm with these parameters K = 830 and 1/n = 0.63. How do I plug in these values to figure out the concentration of AC.Sodium chloride is added slowly to a solution that is 0.010 M in Cu+, Ag+, and Au+. Because solubility "rules" are generalizations, we don't use solubility rules when we have the specific Ksp data available. Instead, here, we can just use the Ksp value for CuCl which is 1.9 × 10–7, for AgCl is 1.6 × 10–10, and for AuCl is 2.0 × 10–13. Based on these specific Ksp values, which compound will precipitate first? All will precipitate at the same time. It cannot be determined. CuCl(s) AgCl(s) AuCl(s)
