Question

What is the equivalent weight of clog in the
following reaction?
CIO3 + Fe 2+ + At → C1-+ Fe3+ +H2O​

Answer 1

ANSWER

FeS+O

2

⟶Fe

+3

+SO

2

Here, as S

2

has oxidation state 2−

Fe has oxidation state 2+

After oxidation Fe has oxidation state 3+

∴ No. of e

−

transferred=3−2=Ie

−

We know,

Equivalent weight=

nfactor

Molecularweight

Here n factor is no. of e

−

transferred as this is a redox reactor.

∴ Equivalent weight=

1

Mol.wt
