Chemistry can be quite a tricky subject for some kids to grasp. What better way to explain fundamental chemistry-related concepts than practical experimentation? Today, we will explore the chemistry concept of oxidation with a simple DIY experiment. Oxidation is a chemical reaction that involves the removal of electrons. Rusting is a good example of this chemical process. Our steel wool and vinegar experiment will help your school-goer understand how certain chemical reactions lead to the process of oxidation.
What you will need
Ask your budding scientist to help you gather these materials to understand how oxidation occurs.
Step-by-step guide
What exactly is happening in this experiment?
In this instance, the temperature of the thermometer rises slowly and steadily. As a consequence of this, the beaker will start getting soggy. Soaking steel wool in the vinegar causes its protective coating to rust. Rusting is essentially the chemical reaction that occurs when iron is exposed to oxygen, after undergoing the process of oxidation. As a consequence of this chemical reaction, heat is created which, in turn, leads to an increase in the temperature of the beaker and on the thermometer as well. This type of chemical reaction is categorised as an exothermic reaction. In such a reaction, energy is released in the form of heat.
