$NaCl + AgNO_{3} \longrightarrow NaNO_{3} + AgCl$

Vedclass · Answer

(B) Oxidation-reduction (redox) reactions are those in which there is a change in the oxidation state of at least one element.$(a)$ $H_{2} (0) + Br_{2} (0) \longrightarrow 2H(+1)Br(-1)$: Oxidation states change.$(b)$ $Na(+1)Cl(-1) + Ag(+1)N(+5)O_{3}(-2) \longrightarrow Na(+1)N(+5)O_{3}(-2) + Ag(+1)Cl(-1)$: There is no change in the oxidation state of any element. This is a double displacement reaction.$(c)$ $2Na_{2}S_{2}O_{3} + I_{2} \longrightarrow Na_{2}S_{4}O_{6} + 2NaI$: The oxidation state of sulfur changes.$(d)$ $Cl_{2} (0) + H_{2}O \longrightarrow H(+1)Cl(-1) + H(+1)O(-2)Cl(+1)$: Chlorine undergoes disproportionation.Therefore,the reaction in $(b)$ is not a redox reaction.
