In the section :Na(2)S(2)O(3)+4Cl(2)+5H(...

In the section `:Na_(2)S_(2)O_(3)+4Cl_(2)+5H_(2)O rarr Na_(2)SO_(4)+H_(2)SO_(4)+8HCl`.
the equivalent weight of `Na_(2)S_(2)O_(3)` will be : `(M=` molecular weight of `Na_(2)S_(2)O_(3)`)

A

M/4

B

M/8

C

M/1

D

M/2

Text Solution

Verified by Experts

The correct Answer is:
B
`Na_(2)overset(+2)S_(2)O_(3)rarrNa_(2)overset(+6)SO_(4)`
the total change in oxidation number `=4xx2=8`
`:. E_(Na_(2)S_(2)O_(3))=(mol.wt.)/(V.f)=(M)/(8)`
