Question
I want to know what happens to chlorine in water after 24 hours. I've been told that it ceases to serve the purpose we put it in water for (namely, to disinfect the water) after 24 hours. If so, what has happened to the chlorine? Has it evaporated or become inert or just what?
It all depends on how much chlorine was added to begin with. At certain levels, the chlorine will be used up in 24 hours and turned inert as a disinfectant. If the water is very clean it will still be there, some will be lost to the air. See the dininfection sections of the following websites on how it works.

By the way, the chlorine smell at a pool. It isn't chlorine, it is chlorine that has reacted with the oil from peoples skin and yes, the reaction of chlorine and urine.
