The student clearly described how the data was obtained and processed, making each procedural step easily understood. The data recording and processing were detailed and precise, with all tables, graphs, and figures appropriately annotated, and the correct application of units, decimal places, and significant figures throughout the work. However, the student did not clearly consider the impact of uncertainties on the data and results, which would enhance the reliability of the findings. Additionally, the data processing section lacked explicit details on how the concentrations of Fe²⁺ ions were calculated from the raw data. Despite these shortcomings, there were no significant omissions or inaccuracies that would hinder the validity of the conclusions drawn.
