Elaboration of the Topic – Types of Mixtures
A mixture is a combination of two or more substances where each component retains its own properties and no new chemical bonds form. Based on how uniformly the particles spread, mixtures fall into two categories:
- Homogeneous Mixtures
- Composition is uniform throughout; you cannot distinguish individual substances.
- Examples: Salt dissolved in water, sugar solution, copper sulphate solution.
- Heterogeneous Mixtures
- Composition is uneven; you can see or separate the different parts.
- Examples: Chalk in water, oil and water, salt and sand.
In this experiment, you’ll add materials like copper sulphate, potassium permanganate, and salt into beakers of water. By stirring and observing:
- Homogeneous mixtures appear clear and consistent—no visible particles remain.
- Heterogeneous mixtures show floating grains, clumps, or uneven coloration.
Understanding these differences helps explain real-world processes—making chemical solutions, cooking recipes, or even tackling pollution in air and water.
Dencity Virtual Science Lab
Performing hands-on trials in a real physics lab or science lab can be expensive, time-consuming, and occasionally unsafe. The Dencity app, available on Android, iOS, and Desktop, brings this experiment to your screen as a fully interactive virtual science lab.
- Cost Efficiency: No need to buy expensive chemicals—just launch the Dencity virtual lab and select “Mixing Substances in Water.”
- Safety: No risk of spills or skin irritation from handling reagents like copper sulphate or potassium permanganate.
- Repeatability: Run the experiment as many times as you like to explore how changing the amount of solute affects mixture type.
- Interactive Learning: Drag and drop substances, adjust quantities with a slider, and observe real-time simulation of particle behavior.

Frequently Asked Questions
- What makes a mixture homogeneous or heterogeneous?
A mixture is homogeneous if its composition is uniform (e.g., salt in water). It’s heterogeneous if you can see individual particles (e.g., sand in water). - Can I change the amount of solute in the experiment?
Yes. In the Dencity app, sliders let you vary solute mass to see how concentration affects mixture type. - Is Dencity suitable for Class 9 and Class 10 Science curricula?
Absolutely. The experiment aligns with both class 9 science and class 10 science learning outcomes. - Do I need special hardware to run the Dencity app?
No. It runs on most Android and iOS devices, desktops, and interactive touch panels. - How does Dencity ensure safety compared to a real lab?
All chemical simulations are virtual—no risk of spills, burns, or harmful fumes. - Can students save and share their results?
Yes. Results export as PDFs or CSVs for easy review and sharing. - What other experiments does Dencity offer?
Explore topics in density, thermodynamics, optics, and more—all within our science lab suite. - Does the app support collaborative group work?
Yes. Our collaborative mode lets up to four students interact in real time, promoting interactive teaching. - Can I access Dencity offline?
The desktop version offers offline mode; mobile devices require occasional internet for license verification. - How do I get technical support or training?
Contact support@dencity.app for tutorials, troubleshooting guides, and live webinars.
