Hydroxylamine reduces iron `III` according to the equaction, `4Fe^(3+) + 2NH_(2)OH rarr N_(2) O + H_(2)O + 4 Fe^(2+) + 4H^(+)`. Orpm `II` thus produced is estimatedf by tiration with standard `KMnO_(4)` solution. The reaction is `MnO_(4)^(-) + 5Fe^(2+) + 8H^(+) rarr Mn^(2+) + 5Fe^(3+) + 4H_(2)O`. A `10 mL` of hydroxyamine solution was diluted to one litere. `50 mL` of this diluted soltuion was boiled with an excess of `Fe^(3+)` solution. The resulting solution required `12mL` of `0.02M KMnO_(4)` solution for complete oxidation of `Fe^(2+)`. Calculate the weight of `NH_(2)OH` in one litre of orignal solution. |
