Question

3. A student followed the procedure of this experiment to determine the percent Naoci in a 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 Na,5,0, solution. A faded price label on the gallon bottle read $0.79. The density of the bleaching solution was 1.10 g/mL. Refer to the post laboratory assignment calculations for h-j. a) Calculate the number of moles of 5,0 required for the titration. b) Calculate the number of moles of Iz produced in the titration mixture. c) Calculate the number of moles of OCI ion present in the diluted bleaching solution titrated. d) Calculate the mass of NaOCI present in the diluted bleaching solution titrated. e) Determine the volume of commercial bleaching solution present in the diluted bleaching solution titrated.

Answer 1

Given the initial Bleaching solution taken = 50 ml

Then it is diluted to 250 ml

That means the total volume of the solution = 250 ml. And the amount of orginal bleaching solution in this 250 ml = 50 ml

Then 20 ml from this 250 diluted solution is taken for titration.

Now if 250 ml of diluted solution contains = 50 ml of commercial bleaching solution,

Then 20 ml of diluted solution contains = 50/250 * 20

= 4 ml of commercial bleaching solution,
