Chlorine evaporation kinetics


New member
How long does chlorine take to evaporate from a 5 gallon bucket of tap water?

I tried to search for this, but only found people propagating what they had heard or just making stuff up. Does anyone have any useful knowledge on chlorine evaporation rate, based on either testing the water for chlorine at various times, or perhaps this can be determined just by manipulating some equations?


-RT * ln(k)
It depends on a huge number of factors. Temperature plays a big role. Other substances in the water play a role. You're not going to get one hard and fast rule.

If you want to remove chlorine there are a number of thiosulfate based products on the market that will do that.
