A) Ferrous nitrate
B) Ferric nitrate
C) A mixture of \[NO\] and \[N{{O}_{2}}\]
D) Nitrosoferrous sulphate
Correct Answer: D
Solution :
Ring test: To the nitrate salt, add freshly prepared \[FeS{{O}_{4}}\] solution and then cone \[{{H}_{2}}S{{O}_{4}}\] carefully by the sides of test-tube. A dark brown ring of ferrous nitrososulphate is formed. \[NaN{{O}_{3}}+{{H}_{2}}S{{O}_{4}}\xrightarrow{{}}NaHS{{O}_{4}}+HN{{O}_{3}}\]\[2HN{{O}_{3}}+6FeS{{O}_{4}}+3{{H}_{2}}S{{O}_{4}}\xrightarrow{{}}\] \[3F{{e}_{2}}{{(S{{O}_{4}})}_{3}}+2NO+4{{H}_{2}}O\] \[FeS{{O}_{4}}+NO\xrightarrow{{}}\underset{Ferrous\,nitrososulphate}{\mathop{[Fe.\,NO]S{{O}_{4}}}}\,\]You need to login to perform this action.
