प्रश्न
In the ring test of \[\ce{NO^{-}3}\] ion, \[\ce{Fe^{2+}}\] ion reduces nitrate ion to nitric oxide, which combines with \[\ce{Fe^{2+} (aq)}\] ion to form brown complex. Write the reactions involved in the formation of brown ring.
उत्तर
\[\ce{NO^{-}_{3} + 3Fe^{2+} + 4H^{+} -> NO + 3Fe^{3+} + 2H2O}\]
\[\ce{[Fe(H2O)6]^{2+} + NO -> \underset{(brown complex)}{[Fe(H2O)5 (NO)]^{2+}} + H2O}\]
