To determine the concentration of Vitamin C, students titrate heated samples with potassium iodate in the presence of hydrochloric acid, potassium iodide, and starch indicator. This process requires a high level of precision, accuracy, and teamwork, with students working in groups of three and individually demonstrating their skills using burettes, pipettes, and lab techniques to minimise error and ensure reliable results.

This engaging, hands-on standard showcases the real-world applications of chemistry, connecting scientific theory with everyday life in a meaningful and practical way. Well done to all students for their dedication and focus during this full-day investigation!
