Carbon dioxide can react with water to form carbonic acid, which can lower the pH of a solution. Bromothymol blue is a pH indicator that changes color from blue to yellow in acidic solutions. When carbon dioxide is bubbled through water containing bromothymol blue, the solution will turn yellow due to the decrease in pH caused by the formation of carbonic acid.

What would cause the blue btb solution containing elodea to turn green?
The blue BTB solution turning green in the presence of elodea indicates that photosynthesis is taking place. During photosynthesis, elodea utilizes carbon dioxide and water to produce glucose and oxygen, leading to a change in the color of the indicator solution from blue to green.
What is a waste product of breathing?
Carbon dioxide is a waste product of breathing. When you exhale, you release carbon dioxide that was produced during the process of breaking down food for energy in your body.
If you could break up a carbon dioxide molecule would you still have carbon dioxide?
No, breaking up a carbon dioxide molecule into its constituent atoms (carbon and oxygen) would result in separate carbon and oxygen atoms. The molecular structure and properties of carbon dioxide would no longer exist.
Do you breath out carbon dioxide?
No, I am a computer program and do not have the ability to breathe or produce carbon dioxide.
Why would red blood cells bring carbon dioxide from the bodys cells to the lungs?
Red blood cells transport carbon dioxide from body cells to the lungs because carbon dioxide is a waste product of cellular metabolism that needs to be removed from the body. In the lungs, carbon dioxide can be exhaled out of the body during respiration.
What is a chemical indicator for carbon dioxide?
Bromothymol blue is a chemical indicator that can be used to detect the presence of carbon dioxide. In the presence of carbon dioxide, the indicator changes color from blue to yellow. This change in color indicates the presence of carbon dioxide gas.
What does photosynthesis have to do with the use of Bromothymol Blue?
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.
How do you think bromothymol blue solution works?
Bromthymol Blue, when heated in a solution, indicates carbon dioxide. If there is carbon dioxide in the solution, it will turn bright yellow (when heated).
How do you describe a chemical test to prove we breath in carbon dioxide?
Bromothymol blue Look it up and you'll get your answer
What 2 solutions can be used to test for carbon dioxide?
Two solutions that can be used to test for carbon dioxide are limewater (calcium hydroxide solution) and bromothymol blue indicator. Limewater turns milky when carbon dioxide is present, indicating the formation of calcium carbonate. Bromothymol blue changes color from blue to yellow in the presence of carbon dioxide.
Which chemicals detect carbon dioxide?
Chemical indicators that detect carbon dioxide include bromothymol blue, phenol red, and pH-sensitive dyes like universal indicator. These indicators change color in the presence of carbon dioxide due to a change in pH levels.
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 gas do you give off which causes btb to changes yellow btb?
Carbon dioxide gas will cause bromothymol blue (BTB) to change from blue to yellow. This is due to the acidic nature of carbon dioxide when dissolved in water, which causes the pH to decrease and the BTB indicator to change color.
How can you determine gasses present in solution using the expermints with BTB?
Bromothymol blue (BTB) can change color in the presence of carbon dioxide or acidic solutions, turning from blue to yellow. By observing the color change in a solution with BTB added, you can determine the presence of carbon dioxide or acidity levels, which can help identify certain gases like carbon dioxide in the solution.
How do you text for carbon dioxide?
To test for carbon dioxide, you can bubble the gas through limewater (calcium hydroxide solution). If carbon dioxide is present, it will cause the limewater to turn milky or cloudy due to the formation of calcium carbonate. Another method is using a pH indicator like bromothymol blue, which will change color in the presence of carbon dioxide.
How breumathol blue shows the presence of carbon dioxide?
Bromothymol blue turns green and yellow as CO2 is added to it. I recently performed a lab in a biology class that dealt with this solution. Message me if you want more info.
What is the byproduct of cellular respiration that changes BTB yellow?
Carbon dioxide is the byproduct of cellular respiration that changes bromothymol blue (BTB) from blue to yellow because it forms carbonic acid when it dissolves in water.
