A) \[+2\]
B) \[+3\]
C) \[\pm 1\]
D) \[\pm 4\]
Correct Answer: A
Solution :
Applying the oxidation number rule in \[[Fe{{({{H}_{2}}O)}_{5}}(NO)]S{{O}_{4}}\] (\[\because \] \[{{H}_{2}}O\] and NO are neutral) \[[x+(0)\times 5+0]+(-2)=0\] \[x+0+0-2=0\] Þ \[x=+2\] Hence, oxidation number of Fe is +2.You need to login to perform this action.
