What Is The Pka Of Bromophenol Blue?
The pKa of bromophenol blue is 4.0, indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts. Volatilization from moist soil surfaces is not expected because the acid exists as an anion and anions do not volatilize.
How is the pKa of bromothymol blue determined?
In the experiment the pKa of bromothymol blue (3',3"- dibromo-thymolsulfonephthalein) is determined by the two methods which have been discussed. At pH less than 6, the indicator is yellow and at pH greater than 7.6, the indicator is blue. At an intermediate pH, the blue and yellow combine to yield a green solution.
