![**Understanding Thymol Pink as a pH Indicator**
Thymol pink is an acid-base indicator with a dissociation constant \( K_a = 2 \times 10^{-4} \). It exhibits a color change depending on the pH of the solution: yellow at pH 1 and pink at pH 14.
### Statements to Evaluate
Select all true statements regarding the use of thymol pink as an indicator:
- [ ] It is a good indicator for a weak acid with strong base titration.
- [ ] At pH = 4 it will be yellow.
- [ ] Its end point will occur when the pH is approximately equal to 9.
- [ ] It is a good indicator for strong acid with weak base titration.
- [ ] If it is added to a solution of 1 M sodium nitrite, the solution will turn pink.
Consider the transition range of thymol pink and the pKa value when determining its suitability as an indicator for specific titrations or scenarios.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0259c9da-a893-42a4-9aeb-f2e84d3b7404%2Fcbf712d0-8748-4fcf-937d-ff76c3a5a532%2F4oqy3g_processed.png&w=3840&q=75)
