Interaction of bromophenol blue and related dyes with bovine.

Bromothymol blue (also known as bromothymol sulfone phthalein, Bromthymol Blue, and BTB) is a chemical indicator for weak acids and bases. It is mostly used in.
Spectrophotometric Determination of the pKa of Bromothymol Blue INTRODUCTION Acid-base indicators are compounds that are simply weak acids (or bases) that exhibit.
The pH dependence of binding of bromophenol blue and of bromocresol purple, which has a higher pKa than bromophenol blue, indicated that binding was dependent on.

First pKa values of some acid-base indicators - Gupta - 2006.

An attempt was made to estimate the first pKa values of bromocresol green, bromocresol purple, bromophenol blue, cresol red, and phenol red using a method similar to.
