[SOLVED] Redox titration help
Hi
In class we are doing a redox titration with a diluted bleach solution. We made the aliquot with 5 ml of 10% KI solution and 5ml H2SO4 with 25 ml of the diluted bleach solution. And the burrette solution was sodium thiosulfate @ 0.1 mol L-1. my results were as follows... 18.2, 18.2 and 18.3
OCL- + 2H+ + 2S2O3-2 = Cl- + S4O6-2 +H2O
I know that the average volume used is 18.23. The question asks to calculate the concentration of hypochlorite ions in diluted bleach solution and to calculate the concentration of NaOCl in grams per liter. please could someone help from this point as I am completely stuck...
