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 |

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....

Analysis of bleach involves two sequential redox reactions: First, bleach is reacted in acid solution with excess iodide anion to produce yellow-colored iodine A sample of a new cleaning product, "Joe's Famous Bleach Cleaner," with a mass of 57.0 g, was diluted with an acetic acid solution containing excess I". A small amount of starch indicator solution was then added, turning the solution a deep bluish-purple. The solution was then titrated with 0.470 M sodium thiosulfate, Na2S203, containing the ion...

A scientist is performing a titration of HClO in bleach samples (10.00 mL aliquot) with 0.0500 M NaOH. She does the initial titration with a pH meter, and it is found to take 32.1 mL of base to reach the endpoint, which shows a pH of 10.07. She now wants to prepare a buffered reference solution with the same pH and same ionic strength as the titration solution at the equivalence point (so the titration can be done routinely without the need...
