Questions & Answers

Q: What are indicators and how are they used in the experiment?

Indicators are substances that change color in the presence of acids, bases, or neutral compounds. In the experiment, indicators like red cabbage juice are used to determine the nature of the chemical being tested.

Q: How can one distinguish between acids, bases, and neutral chemicals using indicators?

Acids turn indicators red, bases turn them blue, green, or yellow, while neutral compounds do not change the color of indicators. This color change helps in identifying the chemical properties.

Q: What safety precautions should be taken when conducting experiments with acids and bases?

It's crucial to handle acids and bases with care, especially when using strong chemicals like bleach. Work under adult supervision, wear protective gear, and ensure proper ventilation to avoid any accidents.

Q: How can one create their own indicator using household items?

By boiling red cabbage leaves in water and extracting the purple dye, one can create a simple homemade indicator for the color-changing experiment. This natural indicator is safe and easy to make at home.
