Question

In the colloidal state the particles size ranges:
A) Below $1nm$
B) Between $1nm\text{ }to\text{ }1000nm$
C) Less than $100nm$
D) None of the above

Answer 1

We know that the nature of colloidal solution is also a heterogeneous that is unlike of all and from these solution as well once with two different phase which are Dispersed medium and Dispersed phase and despite of the fact that a colloidal dispersion are mostly unlikely inside a descriptive nature. This is due to the microscopic size of the particles in the solution.

Complete answer:
So as defined a colloid is the mixture which is being consumed of one or more substances of microscopic dispersion with insoluble particles which are being suspended through each one of through all of other materials. After owing to peculiar structures of a colloidal and it had varied physical and throughout a chemical property.

Also the term colloidal of a particle is all about a small amount of matter having odds of size typically for a colloid with phase boundary. The dispersed-phase particles have a diameter between approx $1$ and $1000~nm$.

Similarly we can have that for colloidal particle has size in the range of $1nm-1000~nm$ ,Suspension has particle size of larger than $100~nm$ and for true solution has particle size of less than $1nm$

Note: Note that during observation of a colloidal dispersion under an ultra-microscopic we can have clear understanding the particles are in continuous movement in solution. Therefore the common node between the random zigzag movement or pattern we have that of the particles in colloidal solution is called Brownian effect. Therefore the given movement is mainly due to unique bombardment of molecules present in dispersed mediums on colloidal particles.
