If, under the same suitable conditions, metal A cannot displace metal B from an aqueous solution of its salt, what is the most appropriate conclusion?
Answer and explanation
Correct answer: Metal A is less reactive than metal B.
In a displacement reaction, a more reactive metal displaces a less reactive metal from its salt solution. Since metal A cannot displace metal B, A is less reactive than B. Option B is the opposite conclusion: if A were more reactive, it should displace B.
