Titration of strong base with strong acid, titration of weak acid with strong base, titrations in diprotic systems, finding the end point with a pH electrode,... As the main contents of the document "Chapter 4: Acid-Base Titrations". Invite you to consult the text book for more documents serving the academic needs and research.
To help you further Chemistry document serve the needs of learning and research, invite you to refer to the content of the curriculum lecture 2 "Acid-base equilbrium: Cân bằng axit-bazơ". Contents of lectures presented in: Acid base equilibrium, buffer solution, Acid-base titration, dissociation of acid. Hope lecture content is useful references for you.
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-
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).

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.
