Chlorine is in `+3` oxidation state in

Options

A. HCl
B. `HClO_(4)`
C. ICI
D. `Cl_(2)O`

Answer

D

Explanation

Oxidation state in species `N^(3+)" in "NaNO_(2)`
Minimum oxidation state -3
Maximum oxidation state +5
`NaNO_(2)` (sodium nitrite) acts both as oxidising as well as reducing agent.
`NANO_(2)` as an oxidising agent:
`2NaNO_(2)+2K overset(-1)(I)+2H_(2)SO_(4) to Na_(2)SO_(4)+K_(2)SO_(4)+2NO+2H_(2)O+overset(0)(I_(2)`
`NaNO_(2)` as an reducing agent:
`H_(2)O+NaNO_(2) to NaNO_(3)+H_(2) overset(-2)(O)`
