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

How do you prepare thymol blue indicator?
Bromothymol Blue (BTB)Bromothymol blue is an indicator, a substance that changes color as the pH of a solution changes. Bromothymol blue is yellow in acidic solutions and blue in basic solutions.BTB can be prepared by mixing 0.1 g (a pinch) of bromothymol blue powder in 10 mL of a 4% solution of sodium hydroxide.Add 20 mL of alcohol and dilute to 1 L with distilled water.The solution should be deep blue.If it is green, add sodium hydroxide solution drop by drop until the solution turns blue.Bromothymol blue can be purchased from scientific supply houses.CAUTION: Sodium hydroxide is corrosive; the BTB solution should be prepared in a laboratory. BTB stains hands and clothes. Have students wear goggles and follow safety precautions when using BTB solution.
