The observed spectrum (green) is the sum of the spectra of HA (gold) and of A − (blue), weighted for the concentration of the two species. When a single indicator is used, this method is limited to measurements in the pH range p K a ± 1, but this range can be extended by using mixtures of two or more indicators.

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 ...
