Distillation is a fascinating process that helps us get super clean water by removing any dissolved substances. It’s like a magic trick that scientists often perform in laboratories to make sure the water is as pure as possible.
To carry out distillation, you need some special equipment. The main piece is a round-bottom flask. This flask is where the magic begins!
First, you pour the impure water into the round-bottom flask. Then, you heat the flask. As the water heats up, it starts to turn into vapor, which is just a fancy word for steam. The cool part is that while the water turns into vapor, all the impurities, like salts and minerals, stay behind in the flask.
Once the water becomes vapor, it travels through the neck of the round-bottom flask. This neck is connected to another important piece of equipment called a condenser. The condenser is like a super chill tunnel that cools the vapor down.
As the vapor moves through the condenser, it cools down and turns back into liquid water. This process is called condensation. The newly purified water then drips into another flask attached to the other side of the condenser.
Distillation is a crucial method for getting pure water, especially in places where water quality is a concern. It’s also used in many industries, like making perfumes and even in producing some types of alcohol.
So, next time you drink a glass of water, think about how distillation might have played a role in making it clean and safe for you to enjoy!
Gather some basic materials like a small pot, a lid, and a heat source. Try to create a simple distillation setup at home with the help of an adult. Use it to purify a small amount of saltwater. Observe the process and note down each step as you see the water vaporize and then condense back into liquid.
In groups, assign roles such as water, impurities, vapor, and condenser. Act out the distillation process, showing how water turns into vapor and leaves impurities behind. This will help you visualize and remember each part of the process.
Draw a diagram of the distillation process, labeling each part of the equipment. Use arrows to show the movement of water from liquid to vapor and back to liquid. Share your diagram with classmates and explain the process to them.
Research how distillation is used in everyday products like perfumes or alcoholic beverages. Create a short presentation or poster to share your findings with the class, highlighting the importance of distillation in these industries.
Collect samples of water from different sources, such as tap water, rainwater, and pond water. Use a simple distillation setup to purify each sample. Test the purity of the water before and after distillation using pH strips or a water testing kit, and record your results.

Distillation is a method used to remove soluble substances from water in order to obtain the purest form of water. This process is generally performed in laboratories. The apparatus used for distillation typically includes a round-bottom flask.
In this process, impure water is placed in the round-bottom flask and heated, causing the water to evaporate as vapor while leaving impurities behind in the flask. The water vapor then travels through the neck of the round-bottom flask, which is connected to a condenser.
The condenser cools the vapor, allowing it to condense back into liquid water. This purified water is then collected in another flask that is attached to the other side of the condenser.

This version maintains the original meaning while improving clarity and readability.
Distillation – A method used to separate mixtures based on differences in their boiling points. – In the lab, we used distillation to purify the water by removing the salt.
Water – A transparent, tasteless, odorless, and nearly colorless chemical substance, essential for most forms of life. – Water is often used as a solvent in chemical reactions because it can dissolve many substances.
Flask – A type of laboratory glassware with a narrow neck and a wide base, used to hold and mix chemicals. – The scientist carefully poured the solution into the flask to begin the experiment.
Vapor – The gaseous form of a substance that is normally liquid or solid at room temperature. – When water is heated, it turns into vapor and rises into the air.
Condenser – A device used in the distillation process to cool and condense vapor back into liquid. – The condenser was an essential part of the setup to collect the distilled water.
Impurities – Unwanted substances that are mixed with the main substance, often affecting its purity. – The impurities in the sample were removed through a series of filtration steps.
Condensation – The process by which vapor turns back into liquid when cooled. – During condensation, the water vapor in the air formed droplets on the cold surface of the bottle.
Clean – Free from dirt, impurities, or unwanted substances. – It is important to use clean glassware to ensure accurate results in a chemical experiment.
Process – A series of actions or steps taken to achieve a particular end. – The process of photosynthesis converts carbon dioxide and water into glucose and oxygen.
Equipment – The necessary items for a particular purpose, especially in a laboratory setting. – The lab technician checked that all the equipment was in place before starting the experiment.
