result: the changes in the conductance of iodine solution were the same as those in the iodine ion solution concentration, but contrary to the iodine solution concentration.
结果:电导值的变化规律与碘离子浓度变化规律相同,与碘的浓度变化规律相反。
according to experiments, the properties of solvent may affect the action between solvent and i2 , which is the reason why the colour of iodine solution varies with the solvent.
