Question

Demonstrate the order of the reactivity

Answer 1

Explanation:

Different metals have different reactivities with chemical reagents. The metals that form positive ions by losing electrons more readily. A more reactive metal displaces a less reactive metal from salt solution. Such reactions are called displacement reactions. Consider an example, if a small amount of zinc is dipped in copper sulphate solution, zinc is displaced from copper sulphate. The blue colour of copper sulphate fades and colourless zinc sulphate solution is obtained. Therefore zinc is more reactive than copper.
