Question
If magnesium displaces copper from copper(II) sulfate solution, what can you infer about the reactivity of magnesium compared to copper?
Answer
Magnesium is more reactive than copper because it can displace copper from its compound in the solution.
Explanation
This answer effectively demonstrates the application of displacement reactions to infer reactivity. The question tests the ability to apply knowledge of displacement reactions to draw conclusions about the reactivity series.
Common mistake
Misunderstanding Displacement Reactions
Students often confuse the concept of displacement reactions, thinking that the less reactive metal is the one that displaces the more reactive metal from its compound.
To fix this, remember that in a displacement reaction, it is the more reactive metal that displaces the less reactive metal from its compound. Review the reactivity series to reinforce which metals are more reactive.
