Vedclass · Answer

(C) redox reaction is one in which both oxidation and reduction occur simultaneously,involving a change in the oxidation states of the elements involved.In option $A$,$S$ in $SO_2$ is $+4$ and in $H_2S$ is $-2$,changing to $0$ in $S$. This is a redox reaction.In option $B$,$Cl$ in $KClO_3$ is $+5$,changing to $+7$ in $KClO_4$ and $-1$ in $KCl$. This is a disproportionation redox reaction.In option $C$,$Na_2O + H_2SO_4 \longrightarrow Na_2SO_4 + H_2O$,the oxidation states are: $Na(+1)$,$O(-2)$,$H(+1)$,$S(+6)$. These remain unchanged in the products. This is a neutralization reaction,not a redox reaction.In option $D$,$Na$ changes from $0$ to $+1$ and $O$ changes from $0$ to $-1$. This is a redox reaction.
