In the ring test of NO_3^(-) ion, Fe^(2+) ion reduces nitrate ion to nitric oxide, which combines with Fe^(2+) complex. Write the reactions involved in the formation of brown ring. |

Answer» SOLUTION :The reactions INVOLVED are : `NO_3^(-) + 3FE^(2+) + 4H^(+) to NO + 3Fe^(3+) + 2H_2O` `[Fe(H_2O)_6]^(2+) + NO to underset("Brown COMPLEX ")([Fe(H_2O)_5(NO)]^(2+))+H_2O` |
