A student wanted to determine the percent of NaOCI in a commercial bleaching solution. He diluted 5.00 g of bleach to 100.0 ml. in a volumetric flask. A 25.00 ml. sample of the diluted bleaching solution was mixed with excess acidified potassium iodide solution and titrated with Na,S,O, solution. The titration required 19.30 ml. of 0.1000 M Na,S,O, solution. The series of reactions that take place during this experiment are given below: 21 + oct + 2H 1 + 25,03- + + Ct + H,0 2r + s,0 a- Cakculate the number of moles of OCt in 25.00 ml. diluted bleach and in 100.0 ml. b- Calculate the percentage of NaOCI in the commercial bleach. e- The percent of NAOCI listed on the label of the bieach bottle is 5.25%. Calculate the percent relative error.
