Question 9
When a sample of the CH2CI, layer with a volume of 5.17 mL is collected, it requires
21.11 mL of a titrant solution of S2032- with a concentration of 0.01421 M to reach
the endpoint. The reaction has a 2:1 mole ratio of thiosulfate to iodine. Determine
the concentration (in mol/L) of iodine in the dichloromethane layer. Include only the
numerical answer (no units).
