In a lab, you diluted a sample of bleach to 1/10 concentration in a 250 volumetric flask. Then quantitatively transferred 25 ml of the 1/10 concentration diluted bleach into a beaker and titrated it with a standard sodium thiosulfate solution that has a molarity of 0.1215M. You repeated this 3 times. The data below is the amount of sodium thiosulfate that was titrated in the 3 runs. Calculate the molarity in each run of the diluted bleach and the concentration of undiluted bleach sample. Titration 1: 45.55 ml Titration 2: 45.67 ml Titration 6: 45.58 ml

Question
In a lab, you diluted a sample of
bleach to 1/10 concentration in a 250
volumetric flask. Then quantitatively
transferred 25 ml of the 1/10 concentration diluted bleach into a beaker and
titrated it with a standard sodium thiosulfate solution that has a molarity of
0.1215M. You repeated this 3 times.
The data below is the amount of
sodium thiosulfate that was titrated in
the 3 runs. Calculate the molarity in
each run of the diluted bleach and the
concentration of undiluted bleach
sample.
Titration 1: 45.55 ml
Titration 2: 45.67 ml
Titration 6: 45.58 ml
