(a)
Interpretation:
The characteristic of dispersed phase not being trapped by filter paper applies to whether a true solution, a colloidal dispersion, or a suspension has to be indicated.
Concept Introduction:
- 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.
