Homework Statement
If 5 mL of a bleach sample is diluted to 100 mL and then 30.00 mL of the dilute solution is titrated with 29.65 mL of a 0.1034 M solution of thiosulfate what is the weight percent of hypochlorite in the 5 mL of bleach?
Homework Equations
OCl−(aq) + 2I−(aq) → I2(aq) + Cl−(aq)
First hypochlorite is reacted with idiode
then we titrate the I2 with thiosulfate
I2(aq) + S2O32−(aq) →I−(aq) + S4O62−(aq)
The Attempt at a Solution
I started by finding moles of thiosulfate and related to I2 and relate back to the hypochlorite OCl- then I used those moles to mass of the OCl- and then after that I'm not sure what to do.
