Which of the following is/are used to detect acidic or basic nature of a solution?
- Phenolphthalein
- Metals
- Universal Indicator
- All of these
The Correct Option is D
Solution and Explanation
To detect whether a solution is acidic or basic, several methods can be used:
Phenolphthalein is a pH indicator that is colorless in acidic solutions and pink in basic solutions. It is commonly used to determine the acidity or basicity of a solution.
Metals can react with acids or bases, producing characteristic reactions that help indicate the presence of acids or bases.
Universal Indicator is a combination of several indicators and changes color over a range of pH values, making it useful for detecting both acidic and basic solutions.
The correct option is (D) : All of these
