Interpretation Introduction

Interpretation:

The given characterization which applies to a colloidal dispersion and a suspension are whether true or false have to be indicated.

Concept Introduction:

True solution:

• It is a homogeneous mixture of two or more solutes and solvent.
• It is composed of particles having diameters less than one nanometer.
• Through filtration, solute particles cannot be obtained.

Colloidal dispersion:

• It is a heterogeneous system formed of a dispersed phase and a dispersion medium.
• It is composed of particles having diameters from one-hundred nanometers.
• Particles do not diffuse through parchment paper, but easily diffuse through filter paper.

Suspension:

• It is a mixture in which the solute does not get dissolved, but will be suspended in the liquid and float freely.
• The nature of solution will be heterogeneous.
• It is composed of particles having diameters greater than 1000 nanometers.
• Particles do not diffuse through parchment paper or through filter paper.
