Soap and Detergent Experiment – Understanding Their Cleaning Power
Soap and Detergents are both used for cleaning, but they function differently, especially in the presence of hard water. This experiment helps students understand their chemical behavior, cleaning efficiency, and practical applications.
What Are Soaps?
Soaps are made from natural oils or fats and are the sodium or potassium salts of long-chain fatty acids. They are biodegradable and work effectively in soft water. However, when used in hard water, which contains calcium and magnesium ions, they react to form a sticky white substance called scum, which reduces their cleaning ability.
What Are Detergents?
Detergents are synthetic cleaning agents that work well in both soft and hard water. They do not react with the minerals in hard water to form scum. Instead, they maintain their cleaning power by producing a large amount of foam, even in the presence of minerals. This makes them highly effective for washing clothes and dishes, especially in areas with hard water or in washing machines.
Real-Life Applications
- Soaps are mainly used for personal hygiene, like bathing and handwashing.
- Detergents are widely used for cleaning clothes, dishes, and other household items, particularly in hard water environments.
Observations from the Experiment
- When soap is added to water, it produces less foam and may result in scum formation, especially in hard water.
- When detergent is added, it produces more foam, indicating better cleaning performance in all water types.
Summary Table
| Substance | Foam Formation | Effect on Water |
|---|---|---|
| Soap | Less Foam | Forms Scum |
| Detergent | More Foam | No Scum |
Learn with Dencity – Your Virtual Science Lab
Understanding the difference between soaps and detergents becomes easy and exciting with the Dencity virtual science lab. This experiment, part of the class 10 science curriculum, is available in the Dencity app and allows students to test how soaps and detergents behave in different types of water—without needing a real lab.
With real-time simulations, interactive controls, and safe experimentation, students can explore these concepts deeply. They can change the type of water (soft or hard), test different cleaning agents, and visualize how foam forms—all in a virtual environment.
Dencity for Teachers
Dencity promotes interactive teaching by allowing educators to:
- Demonstrate experiments live in class or online.
- Assign experiments as homework or classwork.
- Track student progress automatically.
- Use drawing and annotation tools to explain concepts better.
This makes lessons more engaging, and students retain information better thanks to visual learning.
Works Perfectly on Interactive Touch Panels
The Dencity app is fully optimized for interactive touch panels in classrooms. Teachers can manipulate experiments directly on-screen using touch gestures, making science come alive in the classroom.

Frequently Asked Questions (FAQs)
- What is the main difference between soap and detergent?
Soap is made from natural fats and works best in soft water, while detergent is synthetic and works well in both soft and hard water. - Why does soap form scum in hard water?
Soap reacts with calcium and magnesium ions in hard water to form scum, which reduces its cleaning effectiveness. - Can detergents be used for bathing?
No, detergents are not suitable for bathing as they can irritate the skin. - What is foam, and why is it important?
Foam is formed when cleaning agents trap air. It indicates the agent’s cleaning effectiveness, especially in detergents. - Why is detergent preferred for washing machines?
Detergents work well in hard water and create more foam, making them ideal for machine use. - Can this experiment be done without a real lab?
Yes, with the Dencity app, students can perform this experiment virtually and safely. - Is this experiment suitable for class 10 students?
Yes, this is part of the class 10 science curriculum and aligns with school standards. - What devices support the Dencity app?
Dencity runs on mobile phones, tablets, and desktop computers. - Can teachers monitor student performance in Dencity?
Yes, teachers can assign tasks and get detailed reports on student progress. - How can schools get started with Dencity?
