Identify A to E

Answer»

SOLUTION :`(A) overset(NaOH Delta) to `(B)`overset(H_(2)O) larr Mg_(3)N_(2)`
`rArr N_(2) has NH_(4)^(o+) ion and (B) is NH_(3)`
`Mg_(3)N_(2) + 6H_(2)O rarr 3Mg(OH)_(2) + 2NH_(3)`
`NH_(4)^(o+) + NaOH rarr Na^(Theta) + NH^(o+) + NH_(3) + H_(2) + H_(2)O`
Resultantsolubleafter `NH_(3)` has escapedcompletelycontains `Na^(o+)` and anior of (A) which alsogivesRingTest of `NO_(3)^(Theta)`
Thus , (A) is `NH_(4)NO_(3)`
`underset((A))(NH_(4)NO_(3)) + NaOH overset(Delta) tounderset((B))(NH_(3) uarr) + NaNO_(3) + H_(2)O`
`- NaNO_(3) +H_(2)SO_(4) rarr NaHSO_(4) + HNO_(3)`
`HNO_(3) rarr H_(2)O +NO`
`[Fe(H_(2)O)_(6)]SO_(4) + NO rarr underset("Brown coloured ring"(C))([Fe(H_(2)O)_(5)NO]SO_(4)+[H_(2)O])`
`underset((A))(NH_(4)NO_(3))overset(Delta)rarr underset((D))(N_(2)O) +underset((E))(2H_(2)O)`
`N_(2)O +H_(2)O rarr underset("Hyponitrocis acid")underset((F))(H_(2)N_(2)O_(2))`
