Question

The acidic aqueous solution of ferrous ion forms a brown complex in the presence of `NO_(3)^(Θ)` by the follwing two steps:
`[Fe(H_(2)O)_(6)]^(2+) +NO_(3)^(Θ) + H^(o+) rarr … + [Fe(H_(2)O)_(6)]^(3+) + H_(2)O`
`[Fe(H_(2)O)_(6)]^(2+) +…rarr… + H_(2)O`
Complete and balance the equations .

Answer 1

Correct Answer - `3[Fe(H_(2)O)_(6)]^(2+)+NO_(3)^(-) +H^(+) to NO +3[Fe(H_(2)O)_(6)]^(3+)`
`[Fe(H_(2)O)_(6)]^(2+) + NO to [Fe(H_(2)O)_(5)]^(2+)+H_(2)O`
