The student provides a focused and detailed description of the main topic, which is to determine whether H+ ions in HCl act as a catalyst in the reaction between hydrochloric acid and sodium thiosulfate. However, the research question lacks detail and the background information provided could be improved in terms of organization and expanded upon some topics. The chemistry is explained through equations, but further information about the characteristics of the reaction is not provided. The methodology is highly appropriate to the topic, focused on answering the research question, and includes appropriate steps to assure the relevancy and validity of the obtained results. The student also shows full awareness of safety hazards, but no ethical or environmental considerations are mentioned.
