Question:
For the $pH$ range of 2.8 to 4.6, which indicator should be preferred?
For the $pH$ range of 2.8 to 4.6, which indicator should be preferred?
Show Hint
Choose indicators whose pH range overlaps the solution's expected pH.
Updated On: Jun 16, 2025
- Phenolphthalein
- Methyl red
- Thymol blue
- Bromophenol blue
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Bromophenol blue has a pH transition range of approximately 3.0 to 4.6, making it ideal for detecting pH changes in the 2.8 to 4.6 range. Other indicators like phenolphthalein and methyl red operate in different pH ranges.
