 True Solution is a homogeneous mixture of two or more substances in which substance dissolved (solute) in solvent has the particle size of less than 1 nm. They are stable as particles do not settle down when the solution is left standing. The particles are invisible even under powerful microscopes and cannot be separated through filter paper, parchment paper or animal membranes. They do not show Tyndell effect. They appear transparent. Simple solution of sugar in water, sodium chloride in water, most of ionic solids in water are examples of true solution.

Suspension is a heterogeneous mixture in which particle size of one or more components is greater than 1000 nm. This solution is an example of suspension. Contrary to True Solution, particles of suspension are big enough to be seen with naked eye. They are not stable as the particles of suspension settle under water due to influence of gravity. The particles of a suspension can neither pass through ordinary filter paper nor through animal membranes. Suspension may or may not show Tyndall effect. When mud is dissolved in water and stirred vigorously, particles of mud are distributed evenly in water. After some time, the particles of this solution settle under water due to influence of gravity. Turmeric in water, sand in water are some examples of suspensions.

Colloidal Solution appears to be homogeneous but is actually a heterogeneous mixture in which particle size of substance is intermediate of true solution and suspension i.e. between 1-1000 nm. Just like true solutions, Colloidal particles are small enough and can neither be seen through naked eye nor by an ordinary microscope. They easily pass through filter paper. But colloidal particles are big enough to be blocked by parchment paper or animal membrane. They are stable as particles do not settle down when the solution is left standing. Colloids show Tyndall effect. Smoke from a fire is example of colloidal system in which tiny particles of solid float in air.

a solution is a well-mixed mixture containing a solvent and at least one solute that has the same properties throughout. a colloid is a mixture containing small, undissolved particles that do not settle out. and a suspension is a mixture in which particles can be seen and easily separated by settling or filtration.

Solution- it is a homogenous can not be separated & cannot be seen its particles even with is in dissolved condition & will never scatter light since its particles are too small...

Colloid- it seems homogenous solution bt it is heterogenous solution in can be separated by some chemical processes & by some machines like through the process of centrifugation,chromatography etc.....its particles can be seen with the help of is scatters light since its particles are medium in size....

Suspension-it is heterogenous can be separated easily by the process of  evoparation, condensation etc.......its particles can be seen easily even with naked is opaque & scatters light.....

Gayathri, its clearly given in our textbooks. Questions which are not there in textbooks willnot ask for exam. Try to learn tb clearly.

In summary:

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. A solution cannot be filtered but can be separated using the process of distillation.

suspension is cloudy and heterogeneous. The particles are larger than 10,000 Angstroms which allows them to be filtered. If a suspension is allowed to stand the particles will separate out.

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. Light passing through a colloidal dispersion, such as smoky or foggy air, will be reflected by the larger particles and the light beam will be visible.

  solutions have the smallest particles in the liquid: solute particles. They are also Homogeneous. (same throughout) Colloids are the second smallest. They are significantly larger than solute particles (which are invisible to the human eye), but are still quite small. They are also not heavy enough to settle out. Suspensions are the largest of them all. They also disperse throughout a liquid or gas, but are large enough to settle out.
