3. Exact titrations Trial 1 2 3 4. Volume of diluted bleach used (mL): 10ml 10ml Final buret reading (mL): 27.5 29 Initial buret reading (mL): 0 0 Volume of 0.0250M Na S203 (mL): 27.5 29 2 Moles of Na $203 6.875 x 10^-4 mol 7.25 x 10^-4 mol Moles of NaOC1 3.44 x 10^-4 mol 3.625 x 10^-4 mol Molarity of NaOCl in diluted bleach (M): 0.034375M 0.03625M Mean molarity (M) : 0.03531M
1. a. Calculate the molarity of the undiluted bleach solution. b.Commercial bleaches such as Clorox are said to contain 5.25% 7.5% NaOCl by weight. Is this correct? Use your results and a density of 1.0 g/mL for the bleach in your calculations. These calculations should reflect the precision of the assumed density.
