What is a colloidal suspension?

Question

The ferrofluid synthesis involved preparation of a colloidal suspension.

What is a colloidal suspension?

Answer 1

It is a heterogenous mixture, where there is partial solubility of the principal solute in both phases of the mixture.

In synthesis - separating these things is a major nightmare and a much dreaded thing that it encountered much too often.

Colloidal suspensions are - basically - a mess!

Answer 2

In general, a colloid or colloidal dispersion is a substance with components of one or two phases, a type of mixture intermediate between a homogeneous mixture (also called a solution) and a heterogeneous mixture with properties also intermediate between the two. Typical membranes restrict the passage of dispersed colloidial particles more than they restrict the passage of dissolved ions or molecules; i.e. ions or molecules may diffuse through a membrane through which dispersed colloidal particles will not. The dispersed phase particles are largely affected by the surface chemistry existent in the colloid.

Answer 3

When the particles (solid) of a substance are suspended uniformly throughout the liquid, I believe that that is called a colloidal suspension.

Answer 4

"However, for simplicities sake, we will use the term colloidal suspension when referring to any substance that is held in a colloidal state (e.g. ionic, plant-derived minerals within a colloidal solution). "

I have no idea!
