An iodine / thiosulfate titration
An iodine / thiosulfate titration Specimen Results (standardising a thiosulfate solution). 3. Rough titre = cm Theory 3. Second titre = cm Aqueous iodine solutions normally contain potassium iodide (KI), 3. Third titre = cm which acts to keep the iodine in solution. This is due to the fact that an 3. Average of accurate titres = cm equilibrium is set up as follows: 3. Volume of iodine solution used in each titration = cm - - I2 + I I3 Concentration of iodine solution = M. - - I3 is much more soluble than I2 and it is as I3 the iodine is kept in solution. Specimen Calculations In this experiment, a standard ( M) solution of iodine is generated VA x MA x nB = VB x MB x nA.
