The relativity of intensity of scattered light (IS) and the concentration of the precipitate (C) isIS = kS * I0 * Cwhere,kS is a constant I0 is the intensity of light.There are different variables that influence the physical properties of the suspension of particles. The intensity of the scattered light depends on the size and shape of the particle despite scattering being related to the concentration of solid particles in solution. Equally concentrated samples which contain precipitates of differing sizes show different levels of scattering.
