Question

Write the difference between true solution, colloidal solution and suspension on basis of size of particles, nature, appearance, visibility, tyndall effect.​

Answer 1

Answer:

Explanation: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.
