Why did the BTB solution in jar B stay blue?
Bromothymol blue is blue in a solution with a pH over 7,6.
What is BTB solution used for?
BTB solution or bromothymol blue solution is an indicator for CO₂ turning a light green or yellow (extreme) depending on the amount of CO₂ indicated. As an student from a school that has recently done this experiment I can verify this information
What household items contain bromothymol blue?
Bromothymol blue has no household uses.
Why doest fresh water containing bromothymol blue turns yellow?
Hydrogen Chloride (HCl) is an acid. Bromothymol blue turns yellow as HCl is placed in it. Acids change the color of bromothymol blue from green-yellow, depending on whether it is a strong acid or a weak acid.
What does photosynthesis have to do with the use of Bromothymol Blue?
Bromothymol Blue is commonly used as an indicator to detect the presence of carbon dioxide in a solution. In the context of photosynthesis, Bromothymol Blue can be used to observe the rate of photosynthesis. When photosynthesis occurs, carbon dioxide is consumed and oxygen is released. By adding Bromothymol Blue to a solution containing a photosynthetic organism, the color change of the indicator can indicate the rate of photosynthesis.
Is bromothymol a base or acid?
The water solution of bromothymol blue is a little acidic.
Will Yellow Bromothymol Blue revert to Green or Blue color after 12 hours?
No. Bromothymol Blue turns yellow in an acidic solution. If it is in the same solution without any additions, it will stay blue after 12 hours or longer. If the solution is altered by adding base, then the Bromothymol Blue will turn blue or green depending on how much base is added to solution.
What happens when you mix bromothymol blue and calcium chloride?
the temperature changes and the color of the solution turns light green
Why doest fresh water snails containing bromothymol blue turns yellow?

Why did the BTB solution in jar B stay blue?
Bromothymol blue is blue in a solution with a pH over 7,6.
Bromothymol blue a base or acid?
yes. bromothymol blue can act as a acid base indicator. becoz in acidic condition(pH:below 7) bromothymol blue is in green colour whereas in alkaline condition(pH: above 7) its colour changes into blue..
What will be the colour of bromothymol blue in a solution of sodium chloride in water?
Sodium Chloride solution has a pH of 7 & the Indicator color is green. Bromothymol blue indicator reflects a pH range of 3.5-9.5
How is bromothymol blue made?
Bromothymol blue solution can be made by adding 20 milliliters of alcohol to 0.1 grams of bromothymol blue powder and 10 milliliters of 4 percent sodium hydroxide solution. Next, add one liter of of distilled water. If it looks green instead of blue, add some sodium hydroxide to it one drop at a time until it turns blue.
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.
What color does the bromothymol blue solution turn in the presence of carbonated water?
