Vedclass · Answer

(B) Step $1$: $A$ redox reaction involves a change in the oxidation state of elements.Step $2$: In option $(A)$, $Zn$ changes from $0$ to $+2$ and $H$ changes from $+1$ to $0$.Step $3$: In option $(B)$, $Al(OH)_3 + 3HCl \rightarrow AlCl_3 + 3H_2O$ is a neutralization reaction where oxidation states remain constant $(Al=+3, O=-2, H=+1, Cl=-1)$.Step $4$: In option $(C)$, $Mg$ changes from $0$ to $+2$ and $O$ changes from $0$ to $-2$.Step $5$: In option $(D)$, $Fe$ changes from $0$ to $+2$ and $Cu$ changes from $+2$ to $0$.Step $6$: Therefore, option $(B)$ is not a redox reaction.
