The protonated form of bromothymol blue has its peak absorption at 427 nm thus transmitting yellow light in acidic solutions, while the deprotonated form has its peak absorption at 602 nm thus transmitting blue light in more basic solutions. [3] In contrast, highly acidic bromothymol blue is magenta in color.

Solution: The main components of a universal indicator, in the form of a solution, are thymol blue, methyl red, bromothymol blue, and phenolphthalein. This mixture is important because each component loses or gains protons depending upon the acidity or alkalinity of the solution being tested. It is beneficial to use this type of universal ...

Place bromothymol blue in a jar with a plant. Bromothymol blue is then "exposed" to carbon dioxide (exhale into jar). Bromothymol Blue is now yellow color. During photosynthesis, the plant takes in carbon dioxide and gives out oxygen. will bromothhymol blue turn blue again I'm not so sure that stomach contents will be blue; the pH of the ...
