Question

Transcribed Image Text:Question 4
A solution of sodium thiosulfate was standardized by dissolving 0.1906 g KIO3 (214.00 g/mol) in water, adding a large excess of KI, and acidifying with HCI. The liberated iodine
required 48.92 mL of the thiosulfate solution to decolorize the blue starch/iodine complex. Calculate the molar concentration of the Na2S2O3.

- 25.00 mL of a solution containing KIO4 is treated with excess potassium iodide. IO4- + 8H+ + 7I- → 4I2 + 4H2O The resulting solution is titrated with 0.15 M sodium thiosulfate pentahydrate. The average titre was 21.76 mL. I2 + 2S2O32- → 2I- + S4O62- What mass of KIO4 (in g) was dissolved in water to make the original solution?arrow_forwardA student dissolved 0.3101 g of Na2C2O4 in 30 mL of water and 15 mL of 3 mol/L H2SO4. She titrated this solution with a KMnO4 solution. What was the molarity of the KMnO4 if it took 24.90 mL of titrant to reach a permanent pale pink equivalence point? The net redox reaction is 2 KMnO4 (aq) + 5 Na2C2O4 (aq) + 8 H2SO4 (aq) → 8 H2O (l) + 10 CO2 (g) + K2SO4 (aq) + 2 MnSO4 (aq) + 5 Na2SO4 (aq) (2 digit response) Answer: 0.037arrow_forwardThe 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.arrow_forward
- You were assigned to assay a product sample of milk of magnesia. A 0.600-g sample was reacted with 25.00 mL 0.10590 N H2SO4 . The excess unreacted acid in the solution required 13.00 mL of 0.09500 N NaOH when titrated to reach the methyl red end point. Determine the dosage strength of the product in terms of % Mg(OH)2 content. Type your answer in 2 decimal places, numbers only.arrow_forwardFor a 50ml beaker, 0.4532g of pure iron III oxide was weighed, to which 1 ml of a concentrated hydrochloric acid solution was added and then 20 ml of deionized water was added to the beaker. After mixing, the resulting solution was transferred to a 50.00 ml flask and the volume was made up with deionized water. Then 15ml of this solution into a second beaker to which 10ml of an iron iii chloride solution of 0.200 M concentration was added. Calculate the final concentration of the iron iii cation solution expressed in mol/L and in g/L, considering that the volumes are additive.arrow_forwardSuppose the Kc value for Cobalt (II) hexahydrate is 6.80 and suppose upon heating the solution turned pink. If a group of student started mixed 10.5 mL of a 1.25 M [Co(H2O)6]2+(aq) solution with 12.5 mL of a 1.55 M solution of NaCl(aq) with 15.25 mL of a 1.39 M [CoCl4]-2(aq) solution then what color is the solution at equilibrium?
