Question

define the sol, solution

Answer 1

sol is a colloidal solution suspension of very small solid particles[1]in a continuous liquid medium. Sols are quite stable and show the Tyndall effect. Examples include blood, pigmented ink, cell fluids and paint.

solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent. The mixing process of a solution happens at a scale where the effects of chemical polarity are involved, resulting in interactions that are specific to solvation. 

Answer 2

A sol is a type of colloid in which solid particles are suspended in a liquid. The particles in a sol are very small. The colloidal solution displays the Tyndall effect and is stable. Sols may be prepared via condensation or dispersion.
