Description

Bromcresol purple (BCP) is a pH indicator that exhibits a color change from yellow in acidic solutions to purple in basic solutions. It is synthesized by the condensation of 5-sulfosalicylic acid with a mixture of cresols. BCP is used in various applications, including as a pH indicator in chemical laboratories, in microbiological media for differentiating bacterial species, and in the determination of the pH of swimming pools. The color change of BCP is due to the presence of two different forms of the molecule, one yellow and one purple. The yellow form is protonated, while the purple form is deprotonated. The equilibrium between these two forms is pH-dependent, and the color change occurs when the pH reaches a certain value. BCP is studied extensively for its use in various applications, including its sensitivity to changes in pH and its ability to differentiate between different bacterial species. The research on BCP aims to explore its potential applications in diverse fields, including analytical chemistry, biochemistry, and microbiology.'
