The equivalent mass of `Na_(2)S_2O_3` as reductant in the reaction, `Na_2S_(2)O_(3)+5H_(2)O+4Cl_(2) rarr 2NaHSO_(4) +8HCl`

A

(molar mass)/1

B

(molar mass)/2

C

(molar mass)/6

D

(molar mass)/8

Text Solution

Verified by Experts

The correct Answer is:
D
`Na_(2)overset(+2)(S_2)O_3rarroverset(+6)(NaHSO_4)`
`{:(overset(+2)(S_2)O_3^(2-)rarr,2overset(+6)(SO_(4)^(2-))),(+4,+12):}`
`E = M/8`
