Bromothymol blue is an indicator which changes colour in the presence of an acid. When carbon dioxide mixes with water it produces carbonic acid (soda water). A pretty common experiment involves putting a respiring organism in water mixed with bromothymol blue, the water should turn yellow as the organism takes in oxygen and produces carbon dioxide. The indicator can be changed back to its original blue colour by removing the carbon dioxide from the water, i.e. putting in a plant to run photosynthesis - drawing out the carbon dioxide to produce oxygen.
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.

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.
Is bromothymol blue in blue food coloring?
No, bromothymol blue is not typically used in blue food coloring. Blue food coloring usually contains synthetic colorants such as Brilliant Blue FCF (Blue 1) or Indigo Carmine (Blue 2), which are specifically approved for food use by regulatory agencies. Bromothymol blue is more commonly used as a pH indicator in laboratories and not intended for consumption.
How does the pH indicator bromothymol blue measure cellular respiration?
He can use a chemical reaction when it is mixed with CO2
What is the action of potassium hydroxide on 0.1 bromothymol blue?
The color is dark blue.
Can you use bromothymol blue in place of bromophenol blue?

What colour is bromothymol blue in water?
Bromothymol blue is blue in neutral or basic solutions, and yellow in acidic solutions.
What colour is bromothymol blue at the 5 pH level?
Bromothymol blue is green at a pH of 5.
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..
Is bromothymol blue in blue food coloring?

Is bromothymol a base or acid?
The water solution of bromothymol blue is a little acidic.
How do bases change the color of bromothymol?
Bases change the color of bromothymol blue indicator from yellow to blue. This color change occurs because in acidic conditions, bromothymol blue appears yellow, while in basic conditions, it shifts to blue.
Can you use bromophenol blue in place of bromothymol blue?
No, bromophenol blue and bromothymol blue are not interchangeable. They have different pH ranges for color changes and may not give accurate results if substituted for each other in experiments or procedures.
What is the action of sodium chloride on 0.1 bromothymol blue?
Sodium chloride will not have any significant impact on bromothymol blue since it is a neutral compound that does not affect the pH indicator properties of bromothymol blue.
Why doest fresh water snails containing bromothymol blue turns yellow?
Bromothymol blue turns yellow when the solution is acidic.
