what are the reaction between sodium meta bi sulphate and
chlorine?
Answer Posted / linto k. john
Sodium Meta Bi Sulfite (SMBS) is used as a dechlorination agent.
It is widely used in the water treatment industry. The free chlorine in water causes oxidation of RO/Nano Filtration membranes and affect the performance of treatment system.
The basic chemistry behind the dechlorination process is as follows
Chlorine may be either chlorine gas or hypochlorites of sodium or calcium.
When combined with water they hydrolyse to form hypochlorous acid.
1. Cl2 + H2O = HOCl + HCl
2. NaOCl + H2O = HOCl + NaOH
3. Ca(OCl)2 + 2 H2O = 2HOCl + Ca(OH)2
Sodium Meta Bi Sulfite dissolves (SMBS) in water to form Sodium Bi sulfite (SBS)
NaS2O5 + H2O = 2NaHSO3
Sodium bi sulfite react with Hypochlorous acid as follows
2NaHSO3 + 2HOCl = Na2SO4 + H2SO4 + 2HCl
