I am having a hard time identifying which indicator to use in a weak acid - strong base titration.
For context, we are titrating a weak acid against a strong base, and the equivalence point was at pH = 5.4. Now, we are given three choices:
- Indicator 1, with pH range 3 - 6.2
- Indicator 2, with pH range 4 - 5.5
- Indicator 3, with pH range 6 - 7.7
Which indicator is the most suitable for the titration? Do we choose the one where the equivalence point pH is at the middle, towards the end, or higher pH range?
