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.
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.
What colour is thymol blue in acid?
It is Red in Strong Acid like pH 1 or 2 and then it's Yellow
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.
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 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 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 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.

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 chemical formula of trypan blue?
what is the chemical formula for thymol blue
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.
What happens when you mix methyl red and thymol blue?
Mixing methyl red and thymol blue will not result in a predictable color change as these indicators have different pH ranges for color changes. Methyl red changes from red to yellow in acidic conditions (pH 4.4-6.2), while thymol blue changes from yellow to blue in the pH range of 8.0-9.6. Combining them may result in a mixture of colors depending on the pH of the solution, but not a specific color change.
