Mathrusri Annapurna %J Journal of Pharmaceutical Education and Research %D 2010 %I Punjab College of Technical Education %X The protonation and complexation equilibria of Ethambutol dihydrochloride have been studied pH-metrically in aqueous medium at an ionic strength of 0.1 mol dm-3 and 303K temperature. Its protonation constants as well as the binary stability constants of Cu2+, Ni2+ and Co2+complexes were evaluated and the best-fit models were chosenbased on the statistical parameters using MINIQUAD75 computer program. The species distribution diagrams of the binary metal complexes are reported. %K Ethambutol %K protonation constants %K stability constants %K MINIQUAD75 %U http://www.pcte.edu.in/jper/issues/2010-june-vol-1-issue-1/paper-5.pdf
