Question

the reaction zinc +copper sulphate solution-----> zinc sulphate solution + copper indicates that's the metal which is placed lower in the the reactivity series is.
​

Answer 1

Answer:

The reaction is a displacement reaction.

Here a more reactive metal displaces a less reactive metal. So zinc here is more reactive than copper and it displaces copper in copper sulphate solution to form zinc sulphate.

The metal that would be placed lower in the reactivity series would be copper.
