Indikator Alami Asam Basa || Natural Acid and Base Indicators || Fun In Chemistry

Summary

In this video, the creator demonstrates how to make natural pH indicators using common household ingredients. The process includes creating indicators from turmeric, hibiscus flowers, and butterfly pea flowers. The creator shows how each indicator reacts to different substances like vinegar, orange juice, and detergent, changing colors to reveal whether the solution is acidic or alkaline. The experiment is easy to follow and uses simple tools like a plastic bottle, spatula, and hot water. The creator emphasizes the usefulness of natural indicators in science experiments and wraps up the video by sharing the successful results.

Q & A

What is the main topic of the video?

The video demonstrates how to create natural acid-base indicators using everyday materials like turmeric, hibiscus flowers, and butterfly pea flowers.

What are the materials needed to create the natural acid-base indicators?

You need containers (such as plastic bottles or Aqua bottles), a mortar and pestle, a spatula, hot water, filter paper, vinegar, lemon, soap water, and the flowers (turmeric, hibiscus, and butterfly pea).

What does the video recommend as a container for the experiment?

The video suggests using plastic bottles or Aqua bottles. If you don't have those, you can also use plastic cups.

What is the purpose of the hot water in the experiment?

The hot water is used to help extract the color and properties from the flowers to create the natural indicators.

How is the turmeric indicator prepared?

The turmeric is grated, and about 100 mL of water is added to create the solution that will serve as an acid-base indicator.

What color change happens when the turmeric solution is exposed to acidic and basic solutions?

When turmeric is exposed to acidic solutions like vinegar and lemon, it turns yellow. When exposed to a basic solution like soap water, it turns orange.

What color does the hibiscus flower solution turn when mixed with acidic or basic solutions?

The hibiscus flower solution turns red when mixed with acidic solutions (like vinegar and lemon) and green when mixed with basic solutions (like soap water).

How does the butterfly pea flower solution react to acidic and basic substances?

The butterfly pea flower solution turns purple in acidic solutions and green in basic solutions.

Why is it important to test with different substances like vinegar, lemon, and soap water?

Testing with different substances allows us to observe how the natural indicators change color, revealing the acidic or basic nature of the solutions.

What is the significance of using natural indicators for acid-base testing?

Natural indicators are a safe and eco-friendly way to demonstrate the properties of acids and bases, offering an alternative to synthetic chemicals.
