Why does adding carbon dioxide to BTB solution cause a color change?

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?
No

What happens if you add phenol red to water and blow in it with a straw?
Just did this in my BIO 100 lab at SDSU so I know this answer... Background: Phenol red is a pH indicator which is yellow in acidic solutions and red in basic solutions. When you blow into the water with the phenol red, you are adding Carbon Dioxide into the solution. Carbon Dioxide would make this solution more acidic. Therefore this presence of Carbon Dioxide would change the solution color from red to a more orange - yellow color. Hope that helps!
Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
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?
The carbon dioxide will change into a milky solution . If we further bubble through lime water the solution we be colourless.
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
