hi, could anyone please help me with the following question:
in storage, why does iodine solution's concentration decrease over time?

thanx.

I would guess sublimation of iodine.

Tina, I think it is because the iodine is evaporating from the solution and
thus decrease its concentration. Radka

Iodine is a good disinfectant ... when it disinfects ... it is no longer iodine
... pathogens are prevelant ...

oh, i'd be guessing, but it could also be dissociating into iodide and
triodide, reaction with water and changing into HI and more iodide,
conversion to hypoiodous acid and iodide. it becomes a dark red
witches brew of different iodine oxidation states.

Actually an Iodine solution is actually a triiodide solution. Iodine is
not very soluble in water, so it is dissolved in a strong potassium
iodid solution.

The loss of concnetration is due to the volatility of iodine and its
attack on organic materials such as dust. You could also have a slight
increase in concentration caused by its oxidation with air.

Iodine as a disinfectant or iodine crystals?
