Bromothymol Blue is a liquid indicator that can detect presence CO2 in water. It changes color from blue to green, as it detects the presence of the CO2 . In very acidic conditions it will turn yellow. It has also been used as an indicator in the NCO (isocyanate) test (where di-n-butylamine is the base and 1N HCl solution is the acid. Green is the endpoint in this titration and yellow is "over-shot". The amine value test in resin chemistry/synthesis also may use this indicator. HCl directly titrates an amine containing resin.
One limitation of Bromothymol Blue is that its color change is affected by pH changes within a narrow range, making it less precise for detecting small pH changes. Additionally, it may not be suitable for use in environments with extreme pH levels due to its limited pH range.
The Bromothymol Blue is a very useful acid-base indicator. However, it cannot be used to know the exact pH of a solution.
This indicator is a true yellow under 6.0 pH and is blue over 7.6 pH. Because of this, if you have a solution pH=1 and a solution of pH =5 will show the same color, yellow, even though the first solution is 10000 times more acidic.( the pH scale is a logarithmic scale)
Also, this indicator can be used to check if a solution is neutral since it has a greenish color when close to pH=7. However, there is an uncertainty in that value, so you can't know if it is truly neutral.
Bromothymol blue is used as pH indicator: under pH=6 is yellow and above pH=7,6 is blue.

Why doest fresh water snails containing bromothymol blue turns yellow?
Bromothymol blue turns yellow when the solution is acidic.
What happens when you mix bromothymol blue and calcium chloride?
Well, honey, when you mix bromothymol blue and calcium chloride, you get a chemical reaction that forms a precipitate. The bromothymol blue changes color from blue to yellow, thanks to the acidic environment created by the calcium chloride. So, in short, you get a colorful chemistry party that's sure to impress your inner science geek.
What happens when you mix NaOH and Bromothymol blue?
When NaOH is added to Bromothymol blue, the solution turns blue due to the increase in pH caused by the base. This color change occurs because Bromothymol blue is a pH indicator that changes color in response to pH levels.
Colour of hydrochloric acid in bromothymol blue?
Hydrochloric acid turns bromothymol blue yellow because the acid changes the pH of the solution, causing the bromothymol blue indicator to shift its color toward the yellow end of the spectrum.
