The bad smell of water containing hydrogen sulfide
can be removed by the action of chlorine. The reaction
is
H2S(aq) + Cl2(aq)-->2HCl(aq) + S(s)
If the hydrogen sulfide content of contaminated water
is 22 ppm by mass, calculate the amount of Cl2
(in grams) required to remove all the H2S from
2.0 . 10 2+ gallons of water. (1 gallon = 3.785 L.)
