What is the function of bromthymol blue in CO2?
Bromthymol blue is used as an indicator to detect the presence of carbon dioxide (CO2) in a solution. It changes color in the presence of acidic conditions, which can indicate the presence of CO2 as it forms carbonic acid when dissolved in water.
What will happen when CO2 is washed with kmno4 water?
When carbon dioxide (CO2) is washed with potassium permanganate (KMnO4) water, the KMnO4 will be reduced by the CO2 to form a brown precipitate of manganese dioxide (MnO2). This reaction can be used to determine the presence of CO2 in a gas sample by observing the color change from purple (KMnO4) to brown (MnO2).
How can one accurately measure CO2 levels in water?
One can accurately measure CO2 levels in water using a pH meter or a colorimetric method. pH meters measure the acidity of the water, which can indicate the presence of CO2. Colorimetric methods involve adding a reagent that changes color in the presence of CO2, allowing for visual measurement of the levels.
How do you know whether co2 is present in something or not?
CO2 has a distinct smell, faint, but still distintict. Also, if you inhale it you will start to pant due to a lack of oxygen. That is how you can tell. Ayraayra: acutally the "panting" or increased breathing rate is due to the build up of CO2 not because the lack of O2.
How can the student make a quantitative observation of the CO2 collected in the balloons?
The student can measure the volume of CO2 collected in each balloon using a graduated cylinder or syringe to calculate the total volume of gas. They could then compare the mass of the balloons before and after the experiment to determine the mass of CO2 collected. Finally, they could use a color-changing pH indicator to analyze the acidity of the collected gas, indicating the presence of CO2.
What happens when bromthymol blue is exposed to CO2?
When bromothymol blue is exposed to CO2, it undergoes a color change. In the presence of CO2, bromothymol blue turns from blue to yellow due to the formation of carbonic acid. This color change can be used as an indicator for the presence of carbon dioxide.
What color does phenol red change to when carbon dioxide is present?
It turns a yellow-ish color when CO2 is added.

What substance is release by the body that affected the color of the limewater?
carbon dioxide (CO2)
What substance is released by the body that affected the color of the limewater?
carbon dioxide (CO2)
What color did mars used to be?
Mars used to be a creamy or beigy colour but has reacted with the CO2 in its atmosphere to become rusty
How would you detect the presence of CO2 in a sample of air?
One common method to detect the presence of CO2 in air is using a CO2 sensor, which measures the concentration of CO2 in the air and provides a numerical output. Another approach is using colorimetric detection kits that change color in the presence of CO2. Additionally, infrared spectroscopy can also be employed for accurate detection of CO2 levels in air samples.

What is a good name for a CO2 car?
It depends on the color red ''The Flame'' black ''The Phantom'' it depends on you also ''Good Luck''
What color does bicarbonate indicator change to?
Bicarbonate indicator changes color from orange-yellow to red when exposed to carbon dioxide. This change is due to the formation of carbonic acid, which shifts the pH of the solution causing the indicator to change color.
