Question

What happens when light is allowed to pass through a suspension

Answer 1

When light is passed through a true solution, the dissolved are too small to deflect light. suspensions may scatter light, but if the number of suspended particles is sufficiently large, the suspension may simply be opaque, and the light scattering would not occur.

Answer 2

When light passes through a true solution, the dissolved particles are too small to deflect the light... Suspensions may scatter light, but if the number of suspended particles is sufficiently large, the suspension may simply be opaque, and the light scattering will not occur
