The student provides a focused and detailed description of the main topic in the body of the Introduction, explaining the investigation of the impact of the initial concentration of H2O2 on the rate of reaction by measuring the change in pH. The student also includes a well-organized background section that provides relevant and focused information on the key concepts necessary for understanding the investigation. The chemistry of the experiment is explained clearly, making it easy for the reader to understand without the need for rereading. The methodology of the investigation is highly appropriate to the topic, with appropriate steps to assure the relevancy and validity of the obtained results. However, the student does not show full awareness of ethical concerns that can arise during the experiment.
