The size of colloidal particle is:

Explanation:

The correct answer is option C, i.e. the size of colloidal particle is between 10^-6 to 10^-9 m i.e between a micrometer (10^-6) and a nanometer (10^-9).

The components of any colloidal solution are -dispersed phase which is analogous to solute and dispersion medium which is analogous to solvent.

The size, more precisely diameter of dispersed phase usually lies between a micrometer and a nanometer. If it exceeds this range, it falls into category of suspension and if it lies below this range, it falls into category of true solution.

Final Answer:

Hence, the correct answer is Option C i.e. between 10^-6 and 10^-9 m.
