Abstract:

Initially colorless and transparent, the sucrose solution exhibited a stunning array of colors when viewed through a polarizer. This study utilized polarization characteristics to explore the variations in beam split capacity among different sucrose solution concentrations, while also tracking the hydrolysis process of sucrose under acidic conditions. The paper further elucidates the scientific principles underlying these experimental phenomena.

Key words: Sucrose, Optical rotation, Colors, Hydrolysis reaction
