REDOX TITRATION - Weebly
chembloginc.weebly.comTo determine the concentration of a sodium thiosulphate (Na2S2O3) by a redox titration with the I2 generated in a reaction with KIO3 using the starch-iodine complex as the indicator. INTRODUCTION In a reaction with the -thiosulphate ion (S2O32-), iodine (I2) is reduced to iodide (I) and the thiosulphate is oxidized to the tetrathionate ion ...
