Abstract: The 59th International Mendeleev Chemistry Olympiad (IMChO) was held in Brazil from May 6 to 12, 2025. The experimental examination of this edition featured four experiments centered on various applications of hydrolysis reactions: hydrolysis of starch and colorimetric determination of glucose concentration (Experiment 1), titrimetric determination of glucose concentration (Experiment 2), hydrolysis of paracetamol and its quantitative determination in pharmaceutical formulations (Experiment 3), and qualitative analysis of drug components (Experiment 4). These experiments encompass both qualitative and quantitative analytical techniques. This article presents a slightly adapted version of the original experimental problems for the reference of chemistry enthusiasts in China.
