Bromthymol blue is blue in a basic solution.
Phenolphthalein is typically used as a base indicator as it changes color in the presence of bases. Bromthymol blue can be used as both an acid and a base indicator, with different color changes for each.
The color of the bromthymol blue solution or blue btb is yellow after you exhaled into it..:)
Bromthymol blue turns yellow in acidic conditions with a pH below 6.0.
An acidic solution will cause bromthymol blue to turn from blue to yellow. This color change occurs due to a change in the pH of the solution, with acidic conditions resulting in the indicator changing to a yellow color.
Bromthymol blue is used as an indicator to detect the presence of carbon dioxide (CO2) in a solution. It changes color in the presence of acidic conditions, which can indicate the presence of CO2 as it forms carbonic acid when dissolved in water.

if the bromthymol blue changed back to blue from a different color that means that different atoms of another element were in the air. if you tested the bb in a test tube and say it was turned yellow and then overnight it turned back to blue-green then it would mean that a certain amount of oxygen went into the test tube to reverse the change. if there was lots of oxygen in the air then the bb would turn completely blue since bb is not really blue but a weird green color.
Having just done an experiment in class I think I can answer this. In a test tube collect some swimming pool water then add some bromthymol blue and phenolphthalein and using pH paper dip it in the solution to determine the pH.
Bromthymol blue was used in the experiment as an indicator to monitor changes in pH. It changes color in response to pH changes, turning from blue to yellow in an acidic environment and blue to green in a neutral to basic environment. This allows us to visually track any changes in pH during the experiment.
No, bromthymol blue is not a living organism. It is a chemical compound commonly used as a pH indicator in laboratories to detect changes in acidity or alkalinity in a solution.
Indicators change color based on the pH of the solution. You want to pick an indicator with a similar pKa (acid-dissociation constant) as the pH at which the reaction becomes what you desire it to be. Examples include phenolphthalein, bromthymol blue, and phenol red.
When 20 drops of bromthymol blue are added to distilled water in a beaker, the solution will change color depending on the pH level of the water. Bromthymol blue is a pH indicator that turns yellow in acidic conditions (pH below 6) and blue in basic conditions (pH above 7), while it remains green in neutral conditions (around pH 7). Since distilled water is typically neutral, the solution will likely appear green. However, if there are any impurities or if the water's pH is altered, the indicator may show a different color.
When bromothymol blue is exposed to CO2, it undergoes a color change. In the presence of CO2, bromothymol blue turns from blue to yellow due to the formation of carbonic acid. This color change can be used as an indicator for the presence of carbon dioxide.
