Question

how can we distinguish between a collidal and a true solution? explain with the help of diagram.​

Answer 1

Answer:

BASIS FOR COMPARISON TRUE SOLUTION COLLOIDAL SOLUTION SUSPENSION

TRUE SOLUTIONS

True solutions are the type of mixtures, where the solute and solvents are properly mixed in the liquid phase.

example- Sugar solution in water.

Nature of the solution- homogeneous

External appearance

- transparent

size of particles- <1 nm

diffusion- diffuses through filter paper and semi permeable membrane

will not sediment

shows tyndall effect

shows brownian motion

COLLOIDAL SOLUTION

Colloidal solutions are the type of mixture, where the solute (tiny particles or colloids) is uniformly distributed in the solvent (liquid phase).

example- starch dissolved in water

nature-heterogeneous

translucent

size 1 to 1000nm

Particles of the colloidal solutions do not diffuse or pass through membrane, but it is easy through filter paper.

Particles or colloids will not sediment.

The particles in the colloidal solution are visible through the electron microscope, but not through the naked eye.

Tyndall effect is shown by the colloids in the colloidal solution

Particles in the colloidal solution show Brownian movements.

SUSPENSION

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- soil dissolved in water

nature- heterogeneous

appearence- opaque

size- >than 1000nm

Particles of the suspension do not pass through membrane or filter paper.

Particles will get sediment.

The particles in the suspension are visible through naked eyes as well as under the electron microscope.
