Solution, Suspension and Colloid | Chemistry

In this animated lecture, I will teach you about solution, suspension, colloid, true solution, difference between solution suspension and colloid, solution suspension and colloid examples, tyndall effect, examples of solutions, examples of suspension, examples of colloid, difference between solution and suspension, difference between solution and colloid, difference between suspension and colloid, homogeneous mixture, heterogeneous mixture, uniform composition, non uniform composition, etc.
Also, you will learn about the properties of solutions, suspensions and colloids.

Q: What is a solution?
Q: Define solution?
Q: Give examples of solutions?
Ans: Solution is defined as a homogeneous mixture of two or more substances joined together physically.
For example, when you dissolve some salt in the given water, you get a solution. Similarly, when you dissolve some sugar in the water, you again get a solution.
Thus, all homogeneous mixtures are solutions.

Some properties of a solution:

1) Solutions have uniform composition or homogeneous composition throughout its mass.

2) We can not see the particles of a solution with naked eye.

3) The particles of a solution will not settle down if it is allowed to stand for some time.

4) The particles of a solution cannot be separated by filtration.

5) The particles of a solution doesn't scatter light.

Q: What is a suspension?
Q: Define suspension?
Q: Give examples of suspensions?
Q: What are the properties of a suspension?
Ans: Suspension is defined as a heterogeneous mixture of un-dissolved particles in a given medium.
For example, when you add some mud or sand in the water, you form a suspension. Similarly, tea, dust particles in air, oil in water, etc., are  all the examples of a suspension.

Properties of a suspension:

1) Suspensions have non-uniforms composition or heterogeneous composition throughout its mass.

2) We can see the particles of a suspension with naked eye.

3) The particles of a suspension will settle down at the bottom if it is allowed to stand for some time.

4) The particles of a suspension can be separated by filtration.

5) Suspension may or may not scatter a light, but that will be not transparent.

Q: What is a colloid?
Q: Define a colloid?
Q: Give examples of colloids?
Q: What are the properties of a colloid?
Ans: A colloid is defined as a intermediate state of a solution and suspension. The size of  particles of a colloid is smaller than those og a suspension and larger thanthose of a solution.
For example, fog, milk, butter, ink, jelly and toothpaste are the different examples of a colloid.

Properties of a colloid:

I)  Colloids have non-uniform composition or heterogeneous composition throughout its mass.

2) We can't see the particles of a colloid with naked eye.

3) The particles of a colloid will not settle down if it is allowed to stand for some time.

4) The particles of a colloid cannot be separated by filtration.

5) The particles of a colloid can easily scatter the light. This effect is known as Tyndall Effect. It is used to distinguishes a colloid from a solution.

Finally, I will teach you about the...
