A 0.2200g sample of 99.35% pure copper wire is dissolved in concentrated nitric acid. After the addition of an excess of potassium iodide, the liberated iodine is titrated using 35.06mLs of sodium thiosulfate soluiton. 100.0mL of a hydrogen peroxide solution is acidified and excess potassium iodide is then added. The liberated iodine is then titrated using the standardized sodium thiosulfate soluiton, 17.31mLs being required.
What should be the concentration of the sodium thiosulfate solution in order that each mL of the solution correspond to exactly 10 mg of the hydrogen peroxide solution?
