I recently did an experiment for the determination of OCl- in bleach. The acutal value in commerical bleach is 5.25%, but when my group did all of the redox titration calculations, the experiment value turned out to be 4.67%. The experimental error was 9.40%. What do these results mean and how can i talk about them in the discussion part of my lab report?
If anyone can help me, it would be really appreciated. Thanks.

Note: since you don't describe the kind of tests you ran, we can't give a good idea of the source(s) of error for the experiment. Did all the groups get the same value, or just yours? Note that commercial bleach is 5.25 % sodium hypochlorite (usually) If you are going by weight, the % of OCl-ion alone, will be lower; by the factor [OCl/NaOCl] (maybe you have already taken this into acccount).
