Hydrogen and its compoundHard
Question
Fe3+ is reduced to Fe2+ by using -
Options
A.H2O2 in presence of NaOH
B.Na2O2 in water
C.H2O2 in presence of H2SO4
D.Na2O2 in presence of H2SO4
Solution
In acidic medium H2O2 oxidises Fe+2 to Fe+3
In alkaline solution H2O2 reduces Fe+3 to Fe+2
case-1
case-2
{Na2O2 + 2H2O → 2NOH + H2O2}
In alkaline solution H2O2 reduces Fe+3 to Fe+2
case-1
case-2
{Na2O2 + 2H2O → 2NOH + H2O2}
