The amount of I, (aq) in a solution can be determined by titration with a solution containing a known concentration of S,0, (aq) (thiosulfate ion). The determination is based on the net ionic equation 2s,0, (aq) + 15 (aq) S,0, (aq) + 31-(aq) Given that it requires 38.6 mL of 0.470 M Na, S,O,(aq) to titrate a 10.0 mL sample of I, (aq), calculate the molarity of I, (aq) in the solution.

Question
The amount of I, (aq) in a solution can be determined by titration with a solution containing a known concentration of S,O, (aq)
(thiosulfate ion). The determination is based on the net ionic equation
2 S,0 (aq) + 1, (aq) → S,0 (aq) + 31-(aq)
Given that it requires 38.6 mL of 0.470 M Na, S,O, (aq) to titrate a 10.0 mL sample of I, (aq), calculate the molarity of I, (aq) in
the solution.
[5] =
M
