Vedclass · Answer

(C) $1$. The reaction $Ag_2O + H_2O_2 	o 2Ag + H_2O + O_2$ is a correct redox reaction where $H_2O_2$ acts as a reducing agent.$2$. The reaction $PbS + 4H_2O_2 	o PbSO_4 + 4H_2O$ is a correct redox reaction where $H_2O_2$ acts as an oxidizing agent.$3$. The reaction $Fe^{2+} + H_2O_2 \xrightarrow{	ext{basic}} Fe^{3+} + 2OH^-$ is incorrect because in a basic medium,$Fe^{2+}$ is oxidized to $Fe^{3+}$ by $H_2O_2$,but the stoichiometry and charge balance are not represented correctly as $2Fe^{2+} + H_2O_2 	o 2Fe^{3+} + 2OH^-$.$4$. The reaction $Mn^{2+} + H_2O_2 \xrightarrow{	ext{basic}} Mn^{4+} + 2OH^-$ is a correct representation of the oxidation of $Mn^{2+}$ to $MnO_2$ $(Mn^{4+})$ in basic medium.
