Question

In a colloidal system, which particles have the size of $1\mathrm{nm}-1000\mathrm{nm}$?

Answer 1

Colloidal system:

• Colloids (also known as colloidal solutions or colloidal systems) are mixtures in which microscopically dispersed insoluble particles of one substance are suspended in another substance.
• The dispersion medium is the substance in which the colloidal particles are distributed in the range of particles from $1\mathrm{nm}-1000\mathrm{nm}$.
• Some examples of a colloidal solution include whipped cream, mayonnaise, milk, butter gelatin, paper, etc.

Hence, in a colloidal system, the dispersion medium particles have the size of $1\mathrm{nm}-1000\mathrm{nm}$.
