At pH 3.0 it has blue colour

Bromophenol Amax or maximum absorbance in spectrophotometer is 590nm I guess so hehe^^ based on my experimental result though!
It is used as a pH (acid-base) indicator, particularly for substances with an expected pH between 3.0 and 4.6. Bromophenol blue turns yellow at or below a pH of 3.0. It turns purple at or above a pH of 4.6.
