ok So, i have a lab question on calculations. so, we mixed the following: 50mL of 0.080M of Dichloromethane + 200mL of DI water in a 500mL E. flask. We then shook the flask for one hour. We then extracted 20mL of the organic layer and put it in a 250mL flask with 10mL of 0.1m KI. We also extracted 50mL of aqueous layer and put it in a 250mL flask with 10mL lf 0.1M KI we then titrated both the aqueous and organic layer. for organic layer, we used 0.1M (S2O3)2- for aqueous layer, we used 0.01M (S203)2- find concentration [I]2 (subscript 2) for aqueous and organic layer aqueous layer was titrated with using 11.25mL to reach end point organic layer was titrated with 62.2mL to reach end point
