(Similarities and Differences between True Solution, Colloidal Solution and Suspension)

Based on the nature of particle size, solutions are classified into THREE categories, namely (1) True Solution, (2) Colloidal Solution and (3) Suspension. Apart from the size differences of particles, these sub-categories of solutions also show considerable difference in their nature, colour, filterability and appearance.

(1). True Solution: a mixture of two or more substances in which the solute is completely dissolve in the solvent. The size of particles in a true solution will be less than 1 nm in diameter.

(2). Colloidal Solution: a heterogenous mixture of two or more substances in which the substance is evenly suspended in the other. The size of particles in a colloidal solution will be larger than that of a true solution and smaller than suspension. The size range of particles in a colloidal solution will be 1 – 1000 nm in diameter.

(3). Suspension: The size of particles in a suspension will be greater than 1000 nm. Suspension is a heterogenous mixture of two or more substances.

The present post describes the Similarities and Differences between True Solution, Colloidal Solution and Suspension with a Comparison Table.

(Difference between Sol and Gel)

Sol, Gel and Emulsion are the different states of colloidal solutions.

Sol: The liquid state of a colloidal solution is called the sol.

Gel: The solid or semi-solid (Jelly like) stage of a colloidal solution is called the gel.

The present post discusses about the Difference between Sol and Gel.

Difference between Colloids and Crystalloids: A Comparison Table


Difference between Colloid and Colloid

Colloids vs Crystalloids
(Difference between Colloids and Crystalloids)

Colloids: Colloids are homogeneous non-crystalline substances containing large molecules or ultramicroscopic particles of one substance dispersed in a second substance. Colloids include gels, sols, and emulsions.  Unlike the suspension, the particles in the colloid do not settle and they cannot be separated out by ordinary filtering or centrifugation.

Crystalloids: Crystalloids are aqueous solutions of salts or minerals that can be crystallized.

Thus the main difference between colloids and crystalloids are their particle size. Both colloids and crystalloids are used as volume expanders and hence have immense applications in the medical field.
