Unformatted text preview: manipulations, we calculated the average molarity of Na2S2O3 to be .107M. Using this data, we were able to manipulate the numbers using a number of calculations. The mass of NaOCl present was about .072g and the mass of the bleach was 1.084g. When the latter is divided by the former, you get an average of 6.65% NaOCl present in commercial bleach Conclusion-A major portion of the calculations was based on mole to mole ratios of the reactions. Without an understanding of these, the calculations would have been impossible. Despite having a low percentage of hypochlorite ions, bleach is still very basic, which demonstrates how powerful each hypochlorite ion actually is....
