Reaction chemistry between NaHS and chlorine (Cl2)
Reaction chemistry between NaHS and chlorine (Cl2)
(OP)
I want to chemically remove chlorine from a brine solution by using NaOH and NaHS.
Typical reactions used in industry are:
2NaOH + Cl2 = NaCl + NaOCl + H2O
and
Na2SO3 + NaOCl = Na2SO4 + NaCl
but if I substitute NaHS for Na2SO3 what is the reaction and what are the reaction products?
Thanks!

RE: Reaction chemistry between NaHS and chlorine (Cl2)
NaHS + NaOH + 2H2O = Na2SO3 + 2H2
In that case hydrogen is form and your vessel should be able to evacuate the non-condensable gas.
From that reaction Na2SO3 could be form and your second pricipale reaction take place (Na2SO3 with NaCL) from the secondary reaction.
If there is a subtitution for NaHS to Na2SO3 then a secondary reaction is eliminate and no hyrdogen will be form.
Then an economical study should be made to identify if the used of Na2SO3 is less costly than using NaHS.
