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.
What colour would a mixture of thymol blue and phenolphthalein go if you added hydrochloric acid?
HCl has a pH of 1 so thymol blue would turn red in this acidic condition. Phenolphthalein is colorless in an acid so what you would see would be red.
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.
Why is thymol blue used as the indicator for titration of acetic acid and naoh?
Thymol blue changes color in the pH range of 8.0 to 9.6, making it suitable for titrations involving acetic acid (pKa ~ 4.75) and sodium hydroxide. At the equivalence point of the titration, the pH is around 8.5, which falls within the indicator's color change range, allowing for a sharp color transition at the endpoint.
What colour would a mixture thymol blue and phenolphthalein go if sodium hydroxide was added?
The mixture would turn from yellow to blue as the pH increases with the addition of sodium hydroxide. Thymol blue changes color from yellow to blue in basic solutions, while phenolphthalein remains colorless in basic solutions.
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.
What does acid do to thymol blue?
Acid turns thymol blue from blue to yellow. This color change is due to the change in the chemical structure of thymol blue in response to the acidic conditions.
What is thymol blue in acid?
It is Red in Strong Acid like pH 1 or 2 and then it's Yellow

What is the absorbance value for thymol?
thymol blue 436, 545 and 595 nm
In which solution will thymol blue indicator appears blue?
Thymol blue indicator appears blue in basic solutions with a pH greater than 8.2.
How does thymol blue react with an base?
Thymol blue is a pH indicator that changes color depending on the acidity or basicity of a solution. In the presence of a base, thymol blue will change from yellow to blue. It is commonly used in titrations to determine the endpoint of a reaction with a base.
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.
What colour is made by mixing bromothymol blue and sulphuric acid?
Mixing bromothymol blue and sulfuric acid would not result in a colour change, as sulfuric acid is a strong acid and bromothymol blue is a pH indicator that changes colour based on the acidity or alkalinity of a solution.
