State whether the following statement is True or False:China rose indi...
The correct answer is option a because:-
Yes, the China rose indicator turns acidic solutions to dark pink (magenta) and basic solutions to green:
How to prepare the indicator
Soak some China rose petals in warm water for a couple of hours. The red-colored solution is the indicator.
How it works
The China rose indicator is a natural indicator that changes color based on the pH of a solution.
Other indicators
Other acid-base indicators include litmus, phenolphthalein, and methyl orange.

State whether the following statement is True or False:China rose indi...
Understanding China Rose Indicator
The statement is indeed **True**. Let's explore why.
What is China Rose Indicator?
- The China rose indicator, also known as hibiscus extract, is a natural pH indicator derived from the petals of the hibiscus flower.
- It contains anthocyanins, which change color based on the acidity or basicity of the solution.
Color Changes in Solutions
- **Acidic Solutions:**
- When added to acidic solutions (like lemon juice or vinegar), the China rose indicator turns **dark pink (magenta)**.
- This color change occurs because the anthocyanins react with hydrogen ions (H⁺) present in acidic environments.
- **Basic Solutions:**
- In contrast, when the indicator is introduced to alkaline or basic solutions (such as baking soda solution), it shifts to a **green** hue.
- This color change indicates a decrease in the concentration of hydrogen ions, resulting in a more neutral or basic environment.
Practical Applications
- The China rose indicator can be used in classrooms and laboratories to visually demonstrate the pH levels of various solutions.
- It serves as an accessible and visually engaging tool to educate students about acids, bases, and the concept of pH.
Conclusion
In summary, the China rose indicator effectively demonstrates acid-base chemistry through its color changes, confirming that the statement is **True**.
