Chemistry Question on Classical Idea Of Redox Reactions – Oxidation And Reduction Reactions

Nitric oxide acts as a reducing agent in the reaction

A

\ce4NH3+5O2>4NO+6H2O\ce{4NH3 + 5O2 -> 4NO + 6H2O}

B

\ce2NO+3I2+4H2O>2NO3+6l+8H+\ce{2NO + 3I2 + 4H2O -> 2NO3^{-} + 6l^{-} +8H^{+}}

C

\ce2NO+H2SO3>N2O+H2SO4\ce{2NO+H2SO3 -> N2O+ H2SO4}

D

\ce2NO+H2S>N2O+S+H2O\ce{2NO + H2S -> N2O + S + H2O}

Answer

\ce2NO+3I2+4H2O>2NO3+6l+8H+\ce{2NO + 3I2 + 4H2O -> 2NO3^{-} + 6l^{-} +8H^{+}}

Explanation

Solution

O.N. of N changes from + 2 to + 5 hence NO is reducing.
