Simple Distillation

Simple distillation is a basic but powerful technique used in science to separate two liquids or a liquid from a solid mixture, based on differences in their boiling points. It is especially useful when one component of the mixture has a much lower boiling point than the other—ideally, a difference of more than 25°C.

What Happens During Simple Distillation?

When you heat a mixture, the more volatile liquid (the one that boils at a lower temperature) turns into vapor first. This vapor rises and passes into a condenser, where it cools down and becomes liquid again. This new liquid is called the distillate, and it is collected in a separate container. Meanwhile, the other component with a higher boiling point stays in the original flask.

Step-by-Step Process:

1. Heat the Mixture – Start heating the solution in a distillation flask.
2. Evaporation – The component with the lowest boiling point vaporizes first.
3. Condensation – The vapor travels into the condenser where it cools down.
4. Collection – The condensed liquid (now separated) is collected in another container.

Real-Life Examples of Simple Distillation:

• Desalination of seawater – Turning salty water into drinkable water.
• Alcohol purification – Separating alcohol from water in beverage industries.
• Solvent recovery – Reusing chemicals in laboratories.

Key Observations:

• If the boiling point difference is less than 25°C, the separation might not work well.
• Higher heat can speed up evaporation but may reduce purity.
• A longer condenser improves how well the vapor turns back into liquid.
• Impurities with high boiling points stay behind in the flask.

Bring Science to Life with Dencity

With the Dencity app, students can now perform the Simple Distillation Experiment virtually—without the need for actual lab setups or handling hot equipment.

Using the Dencity Virtual Science Lab, students can:

• See real-time simulations of the boiling, condensing, and collecting process.
• Adjust the heat level and observe the impact on distillation efficiency.
• Understand the importance of boiling points through interactive learning.
• Avoid safety hazards and practice multiple times at no extra cost.

This experiment is part of the Class 9 Science curriculum, and Dencity makes it accessible to every student, whether at school or home.

Dencity for Teachers

Dencity promotes interactive teaching by allowing teachers to:

• Demonstrate distillation live using virtual experiments.
• Assign homework in under 30 seconds.
• Let students take control during a lesson to perform steps themselves.
• Use real-time data and visuals to explain concepts clearly.

Teachers can also track student performance, provide instant feedback, and make sure each child is involved—even during remote classes.

Works Seamlessly on Interactive Touch Panels

The Dencity app works beautifully on interactive touch panels in classrooms. Teachers and students can perform every step of distillation—just by touching and dragging. This makes it easier for the whole class to learn together and interactively.

10 Frequently Asked Questions

1. What is simple distillation used for?
   It is used to separate liquids with significantly different boiling points.
2. What is the main requirement for simple distillation to work well?
   A boiling point difference of at least 25°C between the two components.
3. Why is a condenser used in distillation?
   It cools the vapor so it turns back into a liquid.
4. What happens to impurities during distillation?
   High-boiling impurities remain in the distillation flask.
