When doing a titration of a 2.310 g sample of bleach, 11.12 mL of a 0.1117 M Na2S2O3 solution was used. How many moles of I2 reacted with the Na2S2O3? How many grams of NaOCl must have been present in the solution? (Hint: calculate moles of NaOCl that had to have been present based on the moles of I2 that were found and convert that to grams.) What is the percent by mass of the NaOCl in the bleach

  • Commercial bleach titration

    A student diluted 50.00 ml of a commercial bleach to 250.00 ml in a volumetric flask. She took a 20.00 ml aliquot of the solution and reacted it with sodium iodide.Then she added a few drops of starch and titrated the solution with .1000 M Na2S2O3. The blue-black color of the solution disappeared after adding 35.50 ml ofthiosulfate solution. Calculate the number of moles of S2O3 2- used in the titration. Jesus Christ.

    Please answer a-j since this is one question. 3. A student followed the procedure of this experiment to determine the percent commercial bleaching solution that was found in the basement of an abandoned house. The student diluted 50.00 mL of the commercial bleaching solution to 250 mL in a volumetric flask, and titrated a 20-mL aliquot of the diluted bleaching solution. The titration required 35.46 mL of 0.1052M Na2S2O3 solution. A faded price label on the gallon bottle read $0.79....

    A 3.00-mL bleach (NaOCl is the active ingredient) sample is mixed with potassium iodide and acid to completely form triiodide (I3 - ) ions. You then titrate the I3 − ions with a thiosulfate (S2O3 2− ) solution you have previously determined to be 0.1306 M. The endpoint is reached when 31.52 mL of the thiosulfate solution is added. What is the molar concentration of the bleach solution? What is its mass percent?
