Introduction
Techniques of separation.
Pre-Requisites:
Basic knowledge about solutions.
Activity:
Take a beaker with salt water and keep in sunlight. After the water gets evaporated ,observe only salt remains in the beaker
Real Life Question:
Techniques of separation.
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Volatile | The tendency of a substance to vaporize |
| No volatile | The resistivity of a substance to vaporize |
| Evaporation | Evaporation is a type of vaporization of liquid. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Separation by evaporation list | A list of solutions where we can use separation by evaporation technique |
Real life uses :
Salt is separated from water using evaporation technique
Practical examples around us
| Examples | Explainations |
|---|---|
| When salt water is kept in sunlight, the water evaporates and salt remains. Why? | This is because non volatile solute (salt) is mixed with volatile solvent (water).So the water which is volatile gets evaporated leaving salt behind. |
What you learn in Theory:
Separation by evaporation technique.
What you learn in Practice:
Where separation by evaporation can be used in separating solute from solvent.
