State distinguishing characteristics of solutions, colloids and suspension on the basis of
a) Filterability
b) Settling of particles
c) Appearance
d) Tyndall effect
e) Size of the particles.
Answers
Explanation:
If a suspension is allowed to stand the particles will separate out. A colloid is intermediate between a solution and a suspension. While a suspension will separate out a colloid will not. Colloids can be distinguished from solutions using the Tyndall effect.

Answer:
(a) 1. A solution is always transparent, light passes through with no scattering from solute particles which are molecule in size. The solution is homogeneous and does not settle out. ...
2. A suspension is cloudy and heterogeneous. ...
3. A colloid is intermediate between a solution and a suspension.
(b) Sand in water is an example of a suspension. A solution is a homogenous mixture of two or more substances where one substance has dissolved the other.
An example of a solution is saltwater.
Colloids are homogenous mixtures where the particles are small enough that they stay suspended.
(c) Solution Colloids Suspensions
Do not separate on standing Do not separate on standing Particles settle out
Cannot be separated by filtration Cannot be separated by filtration Can be separated by filtration
Do not scatter light Scatter light (Tyndall effect) May either scatter light or be opaque
(d) Solution Colloids Suspensions
Do not separate on standing Do not separate on standing Particles settle out
Cannot be separated by filtration Cannot be separated by filtration Can be separated by filtration
Do not scatter light Scatter light (Tyndall effect) May either scatter light or be opaque
(e) On the ground of size of the particles, nature of the solution, the ability of diffusion and sedimentation these solutions can be ...
