Question

Diffusion of solids in liquids .explain in simple words

Answer 1

If a solid is kept in contact with an excess of solvent in which it is soluble, some portion of the solid gets dissolved. We know that this process is known as dissolution of a solid particles into liquid, which takes place due to diffusion of solid particles into the liquid

Diffusion is also defined as the movement of particles from an area of high concentration to an area of low concentration in a given volume of fluid (either liquid or gas) down the concentration gradient.

Therefore, diffusion of solid in liquid simply means the movement of solid molecules into the liquid medium along the concentration gradient.
