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 boiledwith an excessof Fe^(3+) solution. The resulting solution required 12mL of 0.02M KMnO_(4) solutionfor complete oxidationof Fe^(2+). Calculatethe weight of NH_(2)OH in one litre of orignal solution. |
