how can we distinguish between a colidaial and a true solution explain with the help of a diagram
Answers
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 a semi-permeable membrane
will not sediment
shows the 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 the 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
appearance- 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 the Tyndall effect and Brownian movement.
