NEET Chemistry Redox Reactions Questions Solved


In the reaction Na2S2O3 + 4Cl2 + 5H2O → Na2SO4 + H2SO4 + 8HCI the equivalent weight of Na2S2O3 will be

(1) M/4

(2) M/8

(3) M/1

(4) W/2

(M= molecular weight of Na2S2O3)

(2) Na2s+22O→  Na2s+6O4

see the total change in oxidation number = 4 × 2 = 8

ENa2S2O3= mol. wt.V.f= M8
