Sampling Chlorine - Learn Why & How to Use Potassium Iodide

[LatexZone]

Hey guys,

I'm just curious to know, why is it important to sample the air above and the water in the swimming pool for the chlorine level...and I mean, is there a technique which involves potassium iodide and a pipette?

Thanks!
