The student demonstrated a strong understanding of relevant chemical principles and effectively applied them in their research on manganese's role in wastewater treatment. The essay included a clear explanation of the chosen techniques and apparatus, with detailed descriptions of procedures such as the preparation of oxalic acid and the titration with KMnO4. The student incorporated relevant and appropriate source material, primarily from accredited scientific journals, which supported the investigation's focus. However, there was a notable gap in effectively integrating source material throughout the main body of the essay, as proper citations were missing in some sections. Overall, the student maintained an academic tone and consistently used chemical nomenclature, with appropriate use of balanced equations and SI units.
