Redox Titrations

Iodine, I2, reacts with aqueous thiosulfate ion in neutral solution according to the balance equation

I2(aq)+2S2O3^2-(aq)—->S4O6^2-(aq)+2I^-(aq)

How many grams of I2 are present in a solution if 35.20mL of .15M Na2S2O3 solution is needed to titrate the I2 solution?

  1. .0352L(.15MNaS2O3/L)(1molI2/2S2O3)(253.8gI2/1molI2) = .670g I2
