(a) $2KI + H_2O_2 \longrightarrow 2KOH + I_2$
(b) $2FeSO_4 + H_2SO_4 + H_2O_2 \longrightarrow Fe_2(SO_4)_3 + 2H_2O$
(c) $PbS + 4H_2O_2 \longrightarrow PbSO_4 + 4H_2O$
(d) $Ag_2O + H_2O_2 \longrightarrow 2Ag + H_2O + O_2$

Answer 1

d option is correct h2o2 act as reducing agent means dusare ka reduction khudka oxidation Ag2o convert in Ag firstly Ag has +1 os but after rexn Ag
