Question

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

Answer 1

Answer:

Explanation:

The true solution is the homogenous mixture, while Colloidal solution and Suspension are the heterogeneous mixtures of two or more substances. Another difference between these three types of solution is that the True solution is transparent, while the Colloidal solution is translucent and Suspension is opaque.....

Answer 2

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.
• show tyndall effect and brownian movement.

please mark as brainliest. i worked hard for it.

hope it helps you
