BTB is an acid indicator. by adding carbon dioxide to the solution, it will turn into carbonic acid (a weak acid) turns green in low concentration and yellow in high concentration.

Sulfur dioxide and carbon dioxide dissolve in water what colour would their solution change the universal indicator to?
It wouldn't change at all as it is neutral
Does plants change carbon monoxide to carbon dioxide?
plants do not change carbon monoxide into carbon dioxide. they, on the other hand, convert carbon dioxide in to oxygen.
What are the colors of hydrogen carbonate indicator?
The hydrogen carbonate indicator is used to test for carbon dioxide. If it stays in the normal air, it remains red. If there is more than 0.03 percent of carbon dioxide in the air, it would turn yellow. It there is less than 0.03 percent of carbon dioxide it would turn purple.
A carbon atom from carbon dioxide is used to change the five carbon sugar RuBP into?
a six carbon sugar
How would you test a gas to see if it is carbon dioxide?
Carbon dioxide gas is transparent and under normal conditions you do not see it. However, it does form visible bubbles in carbonated beverages. If you put frozen carbon dioxide ("dry ice") in water, the carbon dioxide that bubbles out of the water will look like fog, because it is very cold and causes moisture in the air to condense. But the fog will dissipate and the carbon dioxide will again become invisible.
Does carbon dioxide gas change acidified potassium dichromate solution green?
Yes, carbon dioxide gas will change acidified potassium dichromate solution from orange to green due to the reduction of the dichromate ion to chromium (III) ions in the presence of reducing agents like carbon dioxide.
Sulfur dioxide and carbon dioxide dissolve in water what colour would their solution change the universal indicator to?
It wouldn't change at all as it is neutral
What happens if you add phenol red to water and blow in it with a straw?
If you add phenol red to water and blow in it with a straw, the water will turn slightly acidic due to the carbon dioxide in your breath forming carbonic acid. This will cause the phenol red to change color, typically from red to yellow.
Is freezing carbon dioxide a chemical change or physical change?
Freezing carbon dioxide is a physical change because it undergoes a phase change from a gas to a solid without changing its chemical composition.
Does plants change carbon monoxide to carbon dioxide?
plants do not change carbon monoxide into carbon dioxide. they, on the other hand, convert carbon dioxide in to oxygen.
What colour would Carbon dioxide change limewater to?
Carbon dioxide.
Is opening a soda can a chemical change?
Nope. The pressure keeps the Carbon Dioxide dissolved in the liquid, and when that pressure is relieved, the CO2 rapidly returns to its gaseous state. None of the molecules are reacting or changing, although the CO2 switches from aqueous to gaseous phase.
Carbon dioxide is bubbled with lime water. what do we observe?
When carbon dioxide is bubbled through lime water, the lime water turns milky due to the formation of calcium carbonate, a white precipitate. This is a common test for the presence of carbon dioxide gas.
How does excess carbon dioxide change the acid base condition of a solution?
The CO2 reacts with the H2O to create H2CO3 (Carbonic acid) Carbon dioxide + Water ---> Carbonic acid ----->Bicarbonate ion---> Hydrogen ion
How are we changing the balance of the gases in our atmosphere today?
We are adding more and more carbon dioxide to the atmosphere. This is causing global warming and climate change.
Which organs are oxygen and carbon dioxide changed?
Oxygen and carbon dioxide change in the lungs.
What must be done to carbon dioxide gas to change it to solid?
the cold air can change the carbon dioxide gas to a solid
