1. LEARNING OBJECTIVES
• CAN WATER DISSOLVE ANY
AMOUNT OF SUBSTANCE ?
• SOLUTION
• SATURATED AND UNSATURATED
• CHURNING
• ACTIVITY
2. CAN WATER DISSOLVE ANY AMOUNT OF SUBSTANCE
• We have gone through soluble and insoluble terms in our previous
chapter and this topic somehow connects to that term .
• Soluble is substance that get mix with water .
• Insoluble is substances that do not mix with water .
3. CAN WATER DISSOLVE ANY AMOUNT OF SUBSTANCE
ACTIVITY : Take some water in beaker . And take salt. And go on adding
the salt in water and stir it well . After adding enough quantity of salt we
will notice that some salt is undissolved and settled at bottom . This tells
that no salt can be dissolved in water now .This concludes that this is
saturated solution . This activity can be performed by sugar too .
4. CAN WATER DISSOLVE ANY AMOUNT OF SUBSTANCE
By the activity done we can come to conclusion of dividing
the topic in two :
(1) Saturated Solution
(2) Unsaturated Solution
5. SOLUTION
Solution
• A solution is a homogeneous mixture composed of two or more
substances.
• In such a mixture, a solute is a substance dissolved in another
substance, known as a solvent.
6. SATURATED AND UNSATURATED SOLUTION
• SATURATED : A saturated solution is a chemical solution
containing the maximum concentration of a solute dissolved in
the solvent. For example take a water and sugar . Put the sugar
in water as much as you can . At some point sugar will settle
down . But if we heat the same solution and now add some
more sugar the sugar will be dissolved . This says that sugar
can be added on heating .
• UNSATURATED : solution that contain less amount of solute
in solvent . For example we put half spoon of salt in water .
But we can put more in that if we want till it get saturated .
