32 mL of an aqueous solution of iodine

is titrated with 0.042 M Na2S2O3(aq), with

starch as the indicator:

I2(aq) + 2 S2O2−

3 (aq) −!

2 I−(aq) + S4O2−

6 (aq)

The blue color of the starch-iodine complex

disappears when 34.65 mL of the thiosulfate

solution had been added. What is the molar

concentration of I2 in the original solution?
