Tyndall effect is not found in
Answers
Answer:
The phenomenon where the path of the light beam is visible as a result of scattering of light by colloidal particles is called Tyndall effect. ... So, the Tyndall effect is not observed in true solutions or suspensions.
Let us answer it
Explanation:
Solution
It is formed when solute is dissolved in solvent .
The solutions can be of different types depending upon the size of solute particles :
True solution
Suspension
Colloids
True solutions
(1) A fire solution is a homogenous mixture of solute and solvent
(2) In a true solution the size of particle is about 10-10m
(3) In a true solution the solute particles cannot be seen even with a powerful microscope
(4) The entire solution passes through filter paper
(5) The solute particles do not show tyndall effect
(6) the particles do not settle due to gravity
Colloidal solution
(1) A colloid appears to be homogenous but actually it is a heterogeneous mixture of solute and solvent
(2) In a colloid the size of particles is in between 10-7 and 10-9 m
(3) In a colloid the dispersed particles can be seen with a powerful microscope
(4) The particles can pass through ordinary filter paper
(5) The particles show tyndall effect
(6) The particles do not settle due to gravity
Suspension
(1) A suspension is a heterogeneous mixture of a solid dispersed in a liquid of a gas.
(2) in a suspension the size of particles is greater than 10-7 m
(3) In a suspension the dispersed particles can be seen with the naked eyes (4) The particles cannot pass through filter paper
(5) The particles may or may not show tyndall effect
(6) The particles may settle due to gravity
Tyndall effect
It is the scattering of light by colloidal particles due to which path of light becomes visible .
It is best shown by colloidal particles because of their intermediate size .
This can make colloidal mixtures appear cloudy or opaque
