When we resperate, we release carbon dioxide. Plants take that in to make oxygen. BTB can not do anything with the carbon dioxide. Only if you add a plant in the container with the BTB, you can make it it's blue color again. A fun experiment is to add soda, like coke, to BTB and see if it changes.
Don't blow into it, its bad for your health! Secondly, because of the chemicals and minerals in it.
BTB is and indicator that indicates if a weak acid is present, such as CO2. The BTB is blue when none is present and it will turn yellow when a weak acid is present.
The color of the bromthymol blue solution or blue btb is yellow after you exhaled into it..:)
BTB stains hands and clothes. As carbon dioxide is absorbed from the breath into the solution, forming carbonic acid, the solution changes color from green to yellow.
It forms carbonic acid and turns yellow
BTB indicator can indicate if a substance contains CO2.
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.
Soda effects BTB when you add it to the BTB. Soda has carbon dioxide in it, which makes it foamy. BTB is used as an indicator of chemicals with a weak acid and base. When you add the carbon dioxide it will change into a green like color.

BTB changes color because of the CO2 in chemicals. When we blow into the BTB with a straw, the water vapor fuses with the BTB and change color. Our breath has some acidic characteristics. The BTB changes from blue, its original color to green-yellow, that's proof that what we breath has acidic molecules.
BTB stains hands and clothes. As carbon dioxide is absorbed from the breath into the solution, forming carbonic acid, the solution changes color from green to yellow.
carbon dioxide from the plant and the more yellow the solution is the more Carbon Dioxide there is. The greener or bluer it is, the less carbon dioxide.
It forms carbonic acid and turns yellow
BTB indicator can indicate if a substance contains CO2.
It turns yellow after we exhaled into the btb solution..:)
"Base" causes BTB to stay blue.
