Write two balanced half reactions for the titration of iodine with sodium thiosulfate. Indicate what is being oxidized and what is being reduced. Show the equivalent wt. of I2 = 126.9.
I2 + 2 Na2S2O3 -----> 2 NaI + Na2S2O6
The above reaction is not the answer. I'm not sure what two half reactions are. Also, what is oxidized and what is reduced? and Finally, how can I show the equivalent wt. of I2 = 126.9. Complete answer plz.
