Na 2 S 2 O 3 has molecular mass M. In reaction Na 2 S 2 O 3 + Cl 2 + H 2 O = 2HCl + Na 2 SO 4 + S find the equivalent weight of Na 2 S 2 O 3.

Na2S2Ohas molecular mass M. In reaction    Na2S2O3+ Cl2+ H2O = 2HCl + Na2SO4+ S find the equivalent weight of Na2S2O3.

Equivalent Weight of Na2S2O3 = (Mass of Na2S2O3)/(n-factor)Let mass of Na2S2O3 be M.Change in oxidation state of S = n-factor = +6 – (+4) = 2Equivalent Weight = M/2
