Demonstration experiment on Rayleigh scattering and Mie scattering

When Na2S2O3 reacts with dilute hydrochloric acid,insoluble solid sulfur molecules emerge in the solution.The diameter of the sulfur molecules is less than the wavelength of visible light.Some sulfur molecules can agglomerate to form particles with their diameters similar to or bigger then the wavelength of visible light.If white light passes through the liquid during the reaction,Rayleigh scattering and Mie scattering can be observed.In Rayleigh scattering,the light polarization can also be observed.
