    Phenolphthalein is used as an indicator
  • b)
    Methyl orange is used as an indicator
  • c)
    Methyl red has pKa=6
  • d)
    The pH range for litmus colour change is 3.0 − 4.5 . Therefore, it can be used as an indicator.

Incorrect Statements in Strong Acid/Strong Base Titrations:

Statement C: Methyl red has pKa=6
This statement is incorrect because the pKa value of methyl red is around 5.1, not 6. Methyl red is often used as an indicator in strong acid/strong base titrations due to its color change at a pH of around 5.1.

Statement D: The pH range for litmus color change is 3.0 – 4.5. Therefore, it can be used as an indicator.
This statement is incorrect because the pH range for litmus color change is actually around 6.5 to 8. Litmus is typically used as an indicator in acid-base titrations where the pH falls within this range.
Therefore, the correct statements regarding indicators in strong acid/strong base titrations are:
- Phenolphthalein is used as an indicator
- Methyl orange is used as an indicator
It is important to use the correct indicators in acid-base titrations to ensure accurate endpoint detection based on the color changes at specific pH ranges. Using indicators with incorrect pKa values or pH ranges can lead to inaccurate results and errors in the titration process.
