The student provides a focused and detailed description of the main topic, explaining the determination of the optimal incubation temperature for oxidation of ethanol in Albani Odense Classic beers. The research question is also present but lacks additional comments. The background information provided is relevant and focused, explaining key concepts such as the significance of ethanol, back titration with potassium dichromate, and oxidation reaction. The chemistry of the experiment is well-explained, allowing the reader to easily understand the processes involved. The methodology is highly appropriate to the topic, utilizing back titration with Na2S2O3 to determine the concentration of ethanol in beer samples of different temperatures. The methodology also includes appropriate steps to assure the relevancy and validity of the obtained results, listing and controlling variables such as volume and concentration of solutions, rest time of incubation, etc. Overall, the student demonstrates a good awareness of safety hazards, ethical concerns, and environmental issues that can arise during the experiment.
