eurjchem-371	Narasimham, Lakshmi; Barhate, Vasant Dnyandeo	Physico-chemical characterization of some beta blockers and anti-diabetic drugs - potentiometric and spectrophotometric pKa determination in different co-solvents	2011	11	.pdf	application/pdf	6815	350	55	On the close examination of Bjerrum curves of all the compounds, it is evident that all the compounds belonging to beta blocker class (AML, PRO, ATN, MT and AB) is bases as all the measured apparent pKa (poKa) values shifted to lower pH values from their aqueous pKa values. Potentiometric pKa determination GLpKa automated pKa analyser (Sirius Analytical Instruments Ltd., Forest Row, UK) fitted with combination Ag/AgCl pH electrode was used for determination of dissociation constants.	cache/eurjchem-371.pdf	txt/eurjchem-371.txt
