what are the reaction between sodium meta bi sulphate and
chlorine?
Answer / 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

Question 75 - The molecular weights M in kg / mol of 3 different monomers a, b and c in a polymer are Ma = 14, Mb = 16 and Mc = 18. The fraction of polymer chain X of 3 different monomers a, b and c in a polymer are Xa = 0.5, Xb = 0.3 and Xc = 0.2. (i) Calculate number average molecular weight by using the formula Ma Xa + Mb Xb + Mc Xc. (ii) Calculate weight average molecular weight by using the formula (Ma Xa Ma + Mb Xb Mb + Mc Xc Mc) / (Ma Xa + Mb Xb + Mc Xc). (iii) Calculate the polydispersity by using the answer in (ii) divided by answer in (i). (iv) If the molecular weight of repeat unit is 12, calculate the degree of polymerization by using the formula (Ma Xa + Mb Xb + Mc Xc) / (molecular weight of repeat unit).
