What process caused the liquids to change from blue to yellow?
The process that caused the color change is called cellular respiration. During this process, the snail exhales carbon dioxide, which combines with water to form a weak carbonic acid, which in turn changes the color of the water from blue to yellow.
What is responsible for the color change in Bromothymol blue solution?
What caused the bromothymol blue solution to change color? The bromothymol blue solution changed color because there was a chemical reaction with the carbon dioxide. After the exercising the bromothymol blue turned green faster. This is because the carbon dioxide was expelled into it faster, because of the exercising.
What can be inferred from the color change of the Bromothymol blue solution?
What is the mechanism driving the bromothymol blue solution color change? Bromothymol blue solution is an indicator that changes color in the presence of a weak acid or base. So release of carbon dioxide into water which turns into a weak acid. Therefore the cellular respiration is the driving the color change.
What is the purpose of the Bromothymol blue BTB solution?
Bromthymol Blue is a dye used as an indicator in determining pH. Bromthymol blue is a weak acid. It can be in acid or base form, depending on the pH of the solution. This reagent is yellow in acidic solutions, blue in basic solutions and green in neutral solution.
Does carbon dioxide change color?
The carbon dioxide gas from exhaled breath makes the water slightly acidic which makes the indicator change color.
Why does carbon dioxide cause a color change?
The CO2 is invisible, but since it is heavier than air, it should pour out of the bottle and into the cup of indicator. When the carbon dioxide mixes with the water in the red cabbage indicator, it creates a very weak acid called carbonic acid. This acid reacts with the red cabbage indicator and changes its color.
What is the name of the process that converts oxygen into carbon dioxide?
Every living cell of our body carries out the energy-releasing process of respiration, where glucose (a simple sugar) is slowly “burnt” (oxidised) to give off carbon dioxide (excreted through the lungs) and water.
What is the difference between carbon dioxide and oxygen?
The ”-oxide” part of the word represents oxygen. This means carbon monoxide has one oxygen molecule bound to carbon and carbon dioxide has two oxygen molecules bound to carbon. Carbon dioxide occurs naturally in our atmosphere. It is exhaled by people and animals when we breathe.
What makes co more harmful to animals than CO2?
Carbon monoxide is poisonous, whereas carbon-dioxide is non-toxic in nature. Carbon monoxide is poisonous because it is capable of forming a complex with haemoglobin (carboxyhaemoglobin), which is more stable than the oxygen-haemoglobin complex. Carbon dioxide is not poisonous.
What makes carbon monoxide more harmful to animals than CO2?
Carbon monoxide is very poisonous, whereas carbon dioxide is not at all toxic in nature. The reason why carbon monoxide is poisonous is because it has the capacity of forming a complex with blood as in haemoglobin. A higher concentration of carbon monoxide is known to even lead to death.
