Question

43. In the reaction of oxidation of thiosulphate (mol. mass=112)2s2o3-2--->s4o6-2+2e-
equivalent weight of thiosulphate ion is
a. 56
b. 112
c. 224
d. 28​

Answer 1

Answer:

Equivalent weight = Molecular weight/Nf

Nf = valency /n factor

Oxidation State in S2O3^-2 is +2

S4O6^-2 is +2.5

nf = 0.5×2 = 1

Equivalent weight= 112/1

E = 112
