In the ring test of NO3– ion, Fe2+ ion reduces nitrate ion to nitric oxide, which combines with Fe2+ (aq) ion to form the brown complex. Write the reactions involved in the formation of a brown ring.

In the ring test of NO3– ion, Fe2+ ion reduces nitrate ion to nitric oxide, which combines with Fe2+ (aq) ion to form the brown complex. Write the reactions involved in the formation of a brown ring.
Reaction Involved:
NO3- + 3Fe2+ + 4H+ → NO + 3Fe2 + 2H2O
[Fe(H2O) 6]SO4 + NO → [Fe(H2O) 5NO]SO4 (brown coloured complex)
