Paragraph for Question Nos. 13 to 15
Hydroxylamine reduces iron (III) according to the equation
2NH2OH + 4Fe+3
N2O (g) + H2O + 4Fe+2 + 4H+
Iron (II) thus produced is estimated by titration with a standard permangnate solution. The reaction is
MnO4 + 5 Fe+2 + 8H+ Mn
+2 + 5Fe+3 + 4H2O
A 10 ml sample of hydroxyl amine solution was diluted to 1 litre. 50 ml of this diluted solution was boiled with
excess of iron (III)solution. The resulting solution required 12 ml of 0.02 M KMnO4 solution for complete
oxidation of iron (II) in acidic medium.

02.0125 mol (C)
10002.0125
mol (D) 1000
02.012205 mol
15. Amount of NH2OH present in 50 ml of its diluted solution will be :(A) 0.6 mili mol (B) 0.12 mili mol (C) 1.2 mili mol (D) 6.0 mili mol
