Answer:
Definition
True Solution: A true solution is a homogeneous liquid containing two or more substances.
Colloidal Solution: A colloidal solution is a heterogeneous mixture of two or more substances.
Transparency
True Solution: True solutions are transparent.
Colloidal Solution: Colloidal solutions are translucent.
Particle Size
True Solution: The size of the particles is 1 nm in true solutions.
Colloidal Solution: The size of the particles ranges from 1 nm to 100 nm.
Visibility
True Solution: The particles of true solution are invisible to naked eye and even under powerful microscopes.
Colloidal Solution: The particles of colloidal solution are invisible to naked eye but are visible under powerful microscopes.
Filtration
True Solution: The particles of true solutions cannot be seperated through filtering.
Colloidal Solution: The particles of colloidal solutions can be seperated from filtering through parchment papers.
Settling
True Solution: The particles do not settle at the bottom of the container in true solutions.
Colloidal Solution: The particles of colloidal solutions can settle at the bottom of the container through centrifugation.
Brownian Effect
True Solution: The Brownian effect cannot be observed in true solutions.
Colloidal Solution: The Brownian effect can be observed in colloidal solutions
Answer:
BASIS FOR COMPARISON TRUE SOLUTION COLLOIDAL SOLUTION SUSPENSION
Meaning
True solutions are the type of mixtures, where the solute and solvents are properly mixed in the liquid phase.
Colloidal solutions are the type of mixture, where the solute (tiny particles or colloids) is uniformly distributed in the solvent (liquid phase).
The suspension is the mixture, where the solute does not get dissolved, rather get suspended in the liquid and float freely in the medium.
Example
Sugar solution in water.
Starch dissolved in water.
Soil dissolved in water.
Nature of the solutions
Homogenous.
Heterogenous.
Heterogenous.
External appearance
Transparent.
Translucent.
Opaque.
Size of the particles (in diameter)
<1 nm.
1-1000 nm.
>1000 nm.
Diffusion of the solution through parchment paper
Diffusion of the particles of the true solutions is simple and smooth through parchment and filter paper as well.
Particles of the colloidal solutions do not diffuse or pass through parchment paper, but it is easy through filter paper. Particles of the suspension do not pass through parchment or filter paper.
Sedimentation
Will, not sediment.
Particles or colloids will not sediment.
Particles will get sediment.
Visibility of particles In true solutions, particles are invisible through the naked eye.
The particles in the colloidal solution are visible through the electron microscope, but not through the naked eye.
The particles in the suspension are visible through naked eyes as well as under the electron microscope.
Tyndall effect
The true solution does show the Tyndall effect.
Tyndall effect is shown by the colloids in the colloidal solution.
The particles show Tyndall effect.
Brownian Movements
Particles in the true solution do show Brownian movements. Particles in the colloidal solution show Brownian movements. The particles show Brownian movements
