Question

Define : a) Colloid, b) Sol​

Answer 1

Answer:

COLLOID

A colloid is a mixture in which one substance of microscopically dispersed insoluble particles are suspended throughout another substance. However, some definitions specify that the particles must be dispersed in a liquid, and others extend the definition to include substances like aerosols and gels.

SOL

A sol is a type of colloid in which solid particles are suspended in a liquid. The particles in a sol are very small. Sols may be prepared via condensation or dispersion. ... Adding a dispersing agent may increase the stability of a sol.

Answer 2

a) Colloid

=》In simple terms, we can define colloids as a mixture where one of the substances is split into very minute particles which are dispersed throughout a second substance. The minute particles are known as colloidal particles.

Alternatively, we can also say that colloids are basically solutions in which solute particle size ranges from 1nm – 1000 nm. Colloids are heterogeneous in nature.

b) Sol

=》A sol is a colloid made out of very small solid particles in a continuous liquid medium. Sols are quite stable and show the Tyndall effect. Examples include blood, pigmented ink, cell fluids, paint, antacids and mud. Artificial sols may be prepared by dispersion or condensation.
