The chemical reaction that we will learn about is CHEMICAL DISPLACEMENT. To demonstrate this experiment, we need We will now take a test tube and add a spatula full of copper sulphate into the test tube. Notice the blue colour of copper sulphate. To this, we will add a little water and prepare copper sulphate solution. Now, we have copper sulphate solution in blue colour. To this solution, we will add some zinc granules. When you leave it for some time, Copper settles down, while zinc sulphate remains on top. Let’s now see how to write the equation for this reaction.
