The objective of this work is to compare the optical activity of brown and white sugar solution using polarimeter. Two type of sugar with different weights were used, it dissolved in the same amount of distilled water to make different concentrations. Xenon lamp was used as light source with two wavelengths (red & green) by using the proper filters. Then sucrose solution was put on a cell with 10 cm length, the rotation angle was measured for different concentrations at the same temperature, and the specific rotation was calculated. We found the optical activity of the sucrose depends on the sugar type, concentration, light wavelength and it is biggest for green light than for red one. Beside that we noticed the brown sugar due to the additional component magnesium and potassium has more ability to rotate the polarized light than the white one.
