BTB solution or bromothymol blue solution is an indicator for CO₂ turning a light green or yellow (extreme) depending on the amount of CO₂ indicated.
As an student from a school that has recently done this experiment I can verify this information
BTB (bromothymol blue) solution is a chemical indicator commonly used in science experiments. If consumed, it can cause gastrointestinal irritation, nausea, vomiting, and potential chemical burns in the mouth, throat, and stomach. It is important to seek medical assistance immediately if BTB solution is ingested.
When you mix lemon juice with bromothymol blue (BTB) solution, the color will change from blue to yellow. This is because the acidity of the lemon juice causes the BTB indicator to shift to its yellow color.
When air is pumped into a BTB (Bromothymol blue) solution, carbon dioxide in the air forms carbonic acid when it dissolves in the water, lowering the pH and causing the solution to change color. BTB is an indicator that changes color in response to pH changes, shifting from blue in a basic solution to yellow in an acidic solution.
A BTB (bromothymol blue) solution changes color to yellow after carbon dioxide from exhaled air reacts with water, forming carbonic acid. This change indicates the presence of an acidic solution.
In BTB (Beyond the Box) solution, the color blue typically represents the recommended course of action or the optimal solution to a problem or challenge. It signifies the most effective or efficient approach based on the analysis or evaluation conducted.
In an alkaline solution, bromothymol blue (BTB) turns blue.
It turns yellow after we exhaled into the btb solution..:)

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.
When you mix lemon juice with bromothymol blue (BTB) solution, the color will change from blue to yellow. This is because the acidity of the lemon juice causes the BTB indicator to shift to its yellow color.
Adding NaOH (sodium hydroxide) to BTB (bromothymol blue) will turn the solution blue, as the color of BTB changes depending on the pH of the solution. When NaOH is added, it increases the pH, causing BTB to shift from yellow to blue.
When air is pumped into a BTB (Bromothymol blue) solution, carbon dioxide in the air forms carbonic acid when it dissolves in the water, lowering the pH and causing the solution to change color.

Adding carbon dioxide to bromothymol blue (BTB) solution causes a color change because it forms carbonic acid, which lowers the pH of the solution. BTB changes color in response to pH changes, shifting from blue in a basic solution to yellow in an acidic solution. The increased acidity due to the carbon dioxide causes the solution to turn yellow.
The BTB stands for: Bromothymol Blue Mostly used for testing the water if there is acid or not.
Bromothymol blue (BTB) can change color in the presence of carbon dioxide or acidic solutions, turning from blue to yellow. By observing the color change in a solution with BTB added, you can determine the presence of carbon dioxide or acidity levels, which can help identify certain gases like carbon dioxide in the solution.
