The Doctoral Thesis Abstract: Study on the method for determination of the equilibrium constants of acids-bases in aqueous solution based on the results of potentiometric titration

The target of this project is to construct a general and feasible procedure to determine the acidic equilibrium constants in aqueous solution at 25oC from the data of the potentiometric titration process in a rapid, simple and effective way. Then it will be applied to estimate the equilibrium constants of some new acids.

Using graphics of logarithmic concentration (GLC) in the titration of bases and mixture of bases

The general programme, which is to draw the Graphics of Logarithmic Concentration (GLC) forming the total line, constructed quickly and to exactly determine the pH at the equivalence point and the titration jump in the titration of bases and mixture of bases with strong acid.

Báo cáo Y học: Characterization of heparin binding by a peptide from amyloid P component using capillary electrophoresis, surface plasmon resonance and isothermal titration calorimetry

Division of Medicinal and Natural Products Chemistry, Department of Chemistry and Department of Chemical Engineering, University of Iowa, USA; 2Department of Autoimmunology, Statens Serum Institut, Copenhagen, Denmark Synthetic peptides based on amino-acid residues 27–38 of human serum amyloid P component represent a novel type of heparin binders as they do not contain clusters of basic amino acids or other known features associated with protein or peptide heparin binding.

Chapter 10: Polyprotic Acid-Base Equilibria

Treating Complex Acid-Base Systems Complex systems are defined as solutions made up of: 1) Two acids or bases of different strengths HCl + CH3COOH NaOH + CH3COO2) An acid or base that has two or more acidic protons or basic functional groups H3PO4 Ca(OH)2 .3) An amphiprotic substance that is capable of acting as both acid and base HCO3- + H2O CO32- + H3O+ HCO3- + H2O H2CO3 + OHNH3+CH2COO- + H2O NH2CH2COO- + H3O+ NH3+CH2COO- + H2O NH3+CH2COOH + OH- .

Chapter 9: Monoprotic Acid-Base Equilibria

Solutions and Indicators for Neutralization Titrations A. Standard Solutions: The standards solutions used as titrants for unknown w eak acids or bases are alw ays strong bases or acids, respectively. Standard titrant acids: dilute solutions of HCl, HClO 4 , or H 2 SO 4 . Standard titrant bases: dilute solutions of NaOH, KOH. The primary standards may not be strong acids or bases (e.g., potassium acid phthalate, sodium oxalate, sodium bicarbonate).
