Technically Chlorine doesn't evaporate but it "dies out" when "attacking" chemicals
Yes. That is why chlorine doesnt last long
no
Flowers or plants can not live in chlorine treated water. This is because the chlorine chemicals shutdown the organelles of the plants cells.
ionisation system stay in water whereas chlorine evaporate into the air, Chlorine irritates the skin, the eyes, and the respiratory system.
Yes
The quantity of chlorine released by a bleaching powder when treated with acid.
I don't frickin know
0.2ppm
It takes 5 to 7 days for the chlorine to evaporate
The speed of this depends on pH, temperature and volume of water.
Oh yes a lot and the vapors are causing cancer related problems. It depends on the water source. If it's water from a well it may not. Large cities will have chlorine. Where I am, in Nebraska they do not add chlorine to the water supply. Water that has been treated with chlorine will taste and often smell of chlorine.
Chlorine evaporates for exactly the same reason that any other substance evaporates. For any individual atom or molecule, if the random thermal motion of that particle takes it in the direction of the surface of the liquid, with sufficient speed to overcome the attraction that the liquid exerts, it will evaporate.
