Collect different solutions available at u're home & classify them into true solutions, colloids , suspensions with the help of torche light.Pls reply
Answers
true solutions--- light does not pass through it as the solute molecule is so small
colloids ---light partially pass through it as the size of the solute is 10^-7
suspensions---light can easily pass through it as the size of the molecules is 10^-5
Answer:
Explanation:
A mixture of two or more substances is called a solution.
Types of solution
1. True solutions : These are homogeneous solutions in which the solute is completely dissolved in the solvent.
2. Suspensions: In this type the solute does not dissolve completely and forms a solvent
3. Colloidal solutions: In this type the solute does not dissolve completely but due to the smaller size of the particles it appears as a homogeneous mixture.
The torch light experiment.
- Prepare test tube solutions by mixing clean water with substances from our daily life such as Common salt, sugar, alum, chalk powder, garden soil, egg albumin and fine sand.
- Using the torch we can classify the solutions.
Pass the beam of torch light through the test tube.
True solution: In true solutions the light rays passes through it. So the solutions of salt, sugar and alum powder are true solutions.
Suspensions - Light rays hardly pass through the contents of the suspension and this can be seen in the solution of soil, chalk powder and fine sand in water.
Colloidal solutions - Light rays are scattered by the contents of the test tube containing colloids. Thus the egg albumin and starch solution scatter light rays.
