Question
In a displacement reaction, which species is oxidised and which is reduced? Provide a brief explanation.
Answer
In a displacement reaction, the more reactive metal is oxidised as it loses electrons, while the less reactive metal ion is reduced as it gains electrons. For instance, in the reaction between zinc and copper sulfate, zinc is oxidised and copper ions are reduced.
Explanation
This question assesses the student's ability to identify oxidation and reduction in the context of displacement reactions, reinforcing their understanding of electron transfer.
Common mistake
Misunderstanding Electron Transfer
Students often confuse the concept of electron transfer in displacement reactions, thinking that the metal being displaced is gaining electrons instead of losing them.
To fix this, students should remember that in a displacement reaction, the more reactive metal loses electrons (is oxidised) while the less reactive metal gains those electrons (is reduced).
