The brown complex obtained in the detection of nitrate radical is form – InterviewSolution

1.	The brown complex obtained in the detection of nitrate radical is formulated as [Fe(H_2 O)_5 NO]SO_4. What is the oxidation number of Fe in this complex?
Answer» `+1` `+2` `+3` 0 Solution :Thebrowncomplexobtained in detectionofnitrateradical is `[Fe(H_2 O)_5 NO [ SO_4]or [Fe(H_2O)_5NO]^(2+) SO_(4)^(2-)` thecolourof thecomplexis dueto changetransfer. Thiscomplexformallycontains`Fe(+1)`and `NO^(+)`sinceFe (II)gainsone electron fromNOwhichchangesto `NO^(+)`
