4.1. The list of basic terms, parameters, characteristics it has
to learn the student in preparation for the class:
ACID-BASED TITRATION (neutralization method) is a titrimetric method of analysis based (in aqueous medium) on the neutralization reaction: H 3 O + + OH - 2H 2 O.
Oxidation-titration is a group of titrimetric methods of analysis based on the SPhU of redox processes, which are the most common and versatile methods and allow directly and indirectly to determine inorganic substances, as well as suitable for the determination of many organic compounds. and pharmaceuticals, the vast majority of which are potential reducing agents. Different solutions of oxidizing agents or reducing agents are SPhUd as standard solutions. Depending on the properties of the titrant SPhUd, oxidimetry and reductometry are distinguished. Oxidimetry is a method of determining the reducing agents by titrating them with standard oxidant solutions.
KOMPLEKSONOMETRIYA ( trylonometriya, helatometriya ) - titrimetric method of analysis based on the reaction of soluble, very stable complexes polydentate ligands complexone cations of alkaline earth and heavy metals. The titrants SPhUd are aminodioctic, nitrilodioctic (complexon I, trilon A), ethylenediaminetetraacetic acid (complexon II) and the disodium salt of ethylenediaminetetraacetic acid (complexon III, trilon B, EDTA, which is SPhUd most)
