Metal A is less reactive than metal B. What happens when metal A is placed in the salt of metal B?
Answer and explanation
Correct answer: No displacement will occur
The governing concept is the reactivity series and displacement reaction. A metal can displace another metal from its salt only when it is more reactive than that metal. Since A is less reactive than B, A cannot remove B from its salt solution. Thus no displacement takes place. Option B would be correct only if A were more reactive, while the other options do not describe a valid chemical change.
