Difference between suspension and colloidal sotution

1.	Difference between suspension and colloidal sotution
Answer» Suspensions -\xa0Suspension is a heterogeneous mixture in which particle size of one or more components is greater than 1000nm. When mud is dissolved in water and stirred vigorously, particles\xa0of mud are distributed evenly in water. After some time, the particles of this solution settle under water due to influence of gravity. This solution is an example of Suspension (see picture below). Contrary to True Solution, particles of suspension are big enough to be seen with naked eye.Colloidal Solution -\xa0Colloidal Solution is a heterogeneous mixture in which particle size of substance is intermediate of true solution and suspension i.e. between 1-1000 nm. Smoke from a fire is example of colloidal system in which tiny particles of solid float in air. Just like true solutions, Colloidal particles are small enough and cannot be seen through naked eye. They easily pass through filter paper. But colloidal particles are big enough to be blocked by parchment paper or animal membrane.\xa0
