An iodine / thiosulfate titration

Aqueous iodine solutions normally contain potassium iodide (KI), which acts to keep the iodine in solution. This is due to the fact that an equilibrium is set up as follows: I2 + I - I 3-I3 - is much more soluble than I 2 and it is as I 3 - the iodine is kept in solution. In this experiment, a standard (0.06 M) solution of iodine is generated
