Vedclass · Answer

(D) The color of colloidal solutions depends on the wavelength of light scattered by the dispersed particles. This wavelength further depends on the size and nature of the particles. For colloidal gold,as the particle size (diameter) changes,the scattering properties change,resulting in different colors (e.g.,red,purple,or blue). Therefore,the different colors are due to the different diameters of the colloidal gold particles.

Colloidal gold solutions prepared by different methods have different colors due to:
