Q. What is the size of colloidal particle?
Answer:- Colloidal particles are larger than most simple molecules, but they are small enough not to settle out while standing. This reduces their size to the point where they can be suspended in the fluid by thermal motion if the buoyancy mismatch between the particles and the fluid isn’t too great.
Colloids are a mixture in which one of the components is broken down into very small particles that are spread throughout a second material.
Colloidal particles are the tiniest particles. A colloid is a heterogeneous system in which one material is dispersed as extremely small particles in a dispersion medium.
The particle size difference is the most significant distinction between a solution and a colloid. In a colloid, the dispersed phase may consist of particles of a single macromolecule (such as protein or synthetic polymer) or an aggregate of many atoms, ions, or molecules, whereas in a solution, the constituent particles are ions or tiny molecules.
Colloidal particles are bigger than single molecules but small enough to float. Their diameter ranges from 11 to 1000 nanometres.
