In the ring test of `NO_(3)^(-)` ion, `Fe^(2+)` ion reduces nitrate ion to nitric oxide, which combines with `Fe^(2+)` (aq) ion to form brown complex . Write the reactions involved in the formation of brown ring. |
|
Answer» The chemical reactions involved are : `NO_(3)^(-) (aq)+3Fe^(2+)(aq) +4H^(+)(aq) to NO(g) +3Fe^(3+)(aq)+2H_(2)O(l)` `Fe^(2+)(aq)+NO(g) +5H_(2)O(l) to [Fe (H_(2)O)_(5)NO]^(2+) (aq)` |
