If metal A displaces metal B from an aqueous solution of its salt, but metal B does not displace metal A from a solution of its salt, which metal is more reactive?
Answer and explanation
Correct answer: Metal A
In a displacement reaction, a more reactive metal displaces a less reactive metal from its salt solution. Since metal A displaces metal B and B cannot displace A, A is more reactive than B. If option B were correct, B would be able to displace A from its salt solution.
