How does sprinkling of salt help in clearing the snow covered roads in hilly areas? Explain the phenomenon involved in the process.

Sodium chloride is used to clear snow from roads. Explain.

Explain how the phenomenon of adsorption finds application in the following process : Froth floation process.

What do you understand by the statement 'Light from the sun is unpolarised'? Explain how does sunlight get polarized by the process of scattering.

Adsorption is surface phenomenon, while absorption concerns with the whole mass of the absorbent. In adsorption, the substance is only retained on the surface and does not go into the bulk or interior of the solid or liquid. Absorption implies that substance is uniformly distributed throughout the body of the solid or liquid. In adsorption, the concentration of the adsorbed molecules is always greater in the immediate vicinity of the surface tlian in the free phase. Absorption involves bulk penetration of the molecules into the structure of the solid or liquid by some process of diffusion. Adsorption is a rapid process and equilibrium is attained in a short time. In absorption the equilibrium takes place slowly. Such substance is said to be sorbed and the phenomenon is known as sorption. How does equilibrium affects by adsorption ?
