Metal A is less reactive than metal B. What will happen when metal A is placed in the salt solution of metal B?
Answer and explanation
Correct answer: No displacement reaction will occur
In a displacement reaction, a solid metal can displace the metal present in a salt solution only if it is more reactive. Since metal A is less reactive than metal B, A cannot remove B from B’s salt solution. Therefore, no displacement reaction occurs. Option B would be possible only if A were more reactive than B. Exam tip: A metal higher in the reactivity series displaces a metal lower in the series from its salt solution.
