Bform an amphoteric oxide
Crelease oxygen gas
Ddisplace the less reactive metal
Answer & Solution
Correct answer: D. displace the less reactive metal
1. This is a displacement reaction: Metal A + salt of B → salt of A + metal B, when A is more reactive.
2. So the more reactive metal **displaces** the less reactive one from its solution (e.g. iron displaces copper from CuSO₄).
3. This is the basis for ranking metals in the activity series.
