Sub Topic Name : Separation Of A Mixture Of Two Miscible Liquids |
|
Introduction
Separation of two miscible liquids.
Pre-Requisites:
Basic knowledge on Boiling points.
Activity:
Heat acetone and water and observe the differences in boiling points.
Real Life Question:
Separation of acetone from water.
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| distillation | A method of separation liquids with different Boiling Points |
| Boiling point | A temperature at which the liquid transforms to vapor state. |
| Fractional distillation | A method of separation of liquids with different BP’s, difference between BP <25C |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| BP chart | Understand the BP of liquids and relation between which gets evaporated first. |
Real life uses :
Separation of water from acetone.
Places to visit :
Lab and do the distillation experiment
Practical examples around us
| Examples | Explainations |
|---|---|
| Why is acetone collected from the condenser whereas the water remains in pure state in the flask | This is because BP of acetone is less than water, So acetone vaporizes first and is collected from the condenser |
What you learn in Theory:
Boiling Point, Distillation
What you learn in Practice:
Distillation and its uses in separating two miscible liquids. Importance of BP.
