Question
Which of the following reactions is a displacement
reaction?Solution
In a displacement reaction, a more reactive metal displaces a less reactive metal from its compound. Zinc (Zn), being more reactive, displaces copper (Cu) from copper sulfate (CuSO₄), resulting in zinc sulfate (ZnSO₄) and elemental copper. This type of reaction underscores the reactivity series of metals where zinc proves superior to copper. In contrast, the other listed reactions include a combination reaction (A), a neutralization reaction (C), and a combustion reaction (D), none of which involve displacement of elements.
