Spectrophotometric data of Bromocresol purple (BCP) and Bromocresol green (BCG) a) Absorbance spectra of SM with 0.01% (w/v) BCG at different pH levels. The two wavelength maxima at 440 and 620 nm correspond to the acidic and basic forms of BCG, respectively. b) Comparison of the BCP and BCG calibration curves at 0.01% (w/v) in SM and their respecive color change range (top right). The equations and R2 are displayed in blue and red for the BCG and BPC, respectively. Each point represents the mean of triplicates ± standard deviation (n = 3)
