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 the gas we breath out. But is also the gas trees need to keep alive.
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.
Why would red blood cells bring carbon dioxide from the bodys cells to the lungs?
Gaseous exchange takes place in the alveoli (in the lungs) -Carbon dioxide is a waste product of aerobic respiration, therefore it is transported via the heart to the lungs to be breathed out in exhalation becasue it isn't needed. Hope this helps
How is carbon dioxide removed from the body?
Carbon dioxide is removed from the body through a process called respiration. When we breathe, we inhale oxygen and exhale carbon dioxide. The carbon dioxide is carried in the blood to the lungs, where it is then exhaled out of the body.
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?
lime water turns milky in the presence of CO2 Limewater (a solution of Calcium hydroxide) - when carbon dioxide is blown through the solution, a precipitate of Calcium carbonate is produced. The solution is said to turn "milky" or "cloudy". Bromothymol blue (pH range 2.4 to 4.6) (red in colour) is added to distilled water, which turns it yellow. Carbon dioxide turns the resulting yellow solution green.
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 can Bromothymol Blue pH measure your rate of cellular respiration?
Bromothymol Blue is a pH indicator that changes color in response to acidity levels. During cellular respiration, carbon dioxide is produced, which reacts with water to form carbonic acid, lowering the pH of the solution. By measuring the color change in Bromothymol Blue, you can indirectly assess the rate of cellular respiration: a faster rate of respiration will result in a quicker color change due to increased production of carbon dioxide. Thus, monitoring the color shift provides a visual representation of the cellular respiration rate.
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.
