What colour would thymol blue go if hydrochloric acid was added?
Thymol blue changes color in the presence of acid or base. If hydrochloric acid is added, thymol blue would turn yellow due to the acidic environment.
Why is phenolphthalein a better indicator than thymol blue?
Phenolphthalein is a better indicator than thymol blue for acid-base titrations because phenolphthalein changes color at a pH range of 8.2-10, which coincides with the endpoint of many acid-base reactions. Thymol blue, on the other hand, changes color at a pH range of 8.0-9.6, which may not be as precise for determining the endpoint.
Is thymol blue and brothymol blue the same?
Yes, thymol blue and bromothymol blue are two different pH indicators. Thymol blue has a pH range of 8.0-9.6 and changes color from yellow to blue, while bromothymol blue has a pH range of 6.0-7.6 and changes color from yellow to blue.
