The student outlined the topic of their study effectively at the beginning of the essay, clearly stating the aim to investigate the effect of sulfuric acid concentration on lead-acid cells. The chosen topic was relevant to the IB Chemistry syllabus, specifically within the electrochemistry core concepts. The student provided a clear context by detailing the background of lead-acid batteries, including the electrochemical processes involved, and posed a focused research question that aligned well with the available resources and time constraints. While the methodology section lacked sufficient detail for replication, the student successfully collected sufficient relevant primary data through practical experimentation. Overall, the essay remained focused on chemistry and presented the necessary background for understanding the study.
