Evaluate equivalent weight of A s 2 O 3 :

As2O3+5H2O→2AsO43-+10H++4 e −

Options:

Answer:
B
Solution:

Ered/oxi=Mol.  weight of reductant or oxidantNumber of electrons gained or lost by one molecule reductant or oxidant or valence factor 



EAs2O3=MAs2O34(As26+  ⟶  2As5++ 4 e − )

Per mole 4 e − lose so 'n' factor = 4

Equivalent weight of A s 2 O 3 = M  wt.  of  A s 2 O 3 4
