Abstract A digital experiment for glucose detection by iodimetry was developed based on self-made MXLab-21 advanced digital experiment system. Compared with the traditional iodine method for measuring glucose, the digital experiment does not require I2 and Na2S2O3 standard solution, which is easy to operate and has small experimental error. Moreover, the recorded real-time curve of the change of electric potential with electrolytic time allows the complicated electrolysis and oxidation-reduction titration process to be visualized, allowing students to better understand the microscopic nature of electrolysis and oxidation-reduction reactions. It is conducive to the cultivation of the core quality of chemistry.
