Introduction: Hydrogen peroxide is a clear and colourless substance that has a strong oxidizing characteristic. From the books, “Hydrogen Peroxide: Medical Miracle”[1995] by Douglass and “Applications of hydrogen peroxide and derivatives” [1999] by Jones, hydrogen peroxide can be used in numerous industrial and domestic applications such as a disinfectant, an oxidizer, or treatment for cancer and other diseases. However, hydrogen peroxide can be toxic when highly concentrated in the body. Hydrogen peroxide can easily breakdown into water and a single oxygen molecule through exothermic reaction, but when stored properly at low concentrations, the solution becomes stable. As a molecule, hydrogen peroxide has a double bent structure and is also a polar covalent particle. Due to these properties, hydrogen peroxide can exert the three types of intermolecular forces: Van der Waal’s force, Dipole-dipole force, and hydrogen bonding. According to “Hydrogen Peroxide Background”[2005], 3% hydrogen peroxide is denser and has a higher boiling point than water. For this experiment, the purpose will focus on how hydrogen peroxide concentrations of 0%, 0.75%, 1.5%, 2.25%, and 3% affects the volume of its drop. To obtain different concentrations, 3% hydrogen peroxide will be diluted with varying amounts of distilled water. Each different concentration will then be transferred into a buret in order to find the volume of 50 drops of each solution. This will be done in three trials in order to provide enough data to support a strong analysis and conclusion. By measuring 50 drops, the ability to analyze the volume of a drop will be significantly read using the buret to show the differences between
