Today we will conduct and discuss a Displacement Reaction. For this we will need some crystals of Ferrous Sulfate, pieces of Zinc metal, an empty beaker, stirrer and a glassful of water. We will first make a solution of Ferrous Sulfate. For this place a few crystals of Ferrous Sulfate in the empty beaker. Then add some water to the beaker and stir. After a while you will get a clean solution of Ferrous Sulfate. This solution will be pale yellow in color. To this solution of Ferrous Sulfate we will add a few pieces of Zinc metal. Wait for a while because it will take a while before the reaction starts. 
The left beaker is where the reaction is taking place. The right hand beaker contains freshly prepared Ferrous Sulfate solution. In the left hand beaker the Ferrous Sulfate has reacted with zinc. After a while you can remove the zinc metal pieces from the left beaker with the help of tweezers. In the left beaker Zinc Sulfate solution will be prepared and Iron will be deposited at the bottom of the beaker. This is an example of Displacement Reaction where during a reaction one metal replaces another. Here you can see Iron deposits at the bottom of the beaker.
