Fundamentals of Volumetric Chemical Analysis, Acid/Base Equilibria & Titrations
Some of the most important processes in chemical and biological systems are acid-base reactions in aqueous solutions. At the onset of this unit, a review of the topic of acid-base equilibria, together with the properties of acids and bases is undertaken. This is because the concepts of ionic equilibria and reactions are important for a better understanding of the ideas and workings of acid-base neutralization titrations.
Complex ion Equilibria and Complexometric Titrations
Complex-forming reactions involving many metal ions can serve as a basis for accurate and convenient titrations for such metal ions. These kinds of complex ion titration procedures referred to as complexometric titrations, have high ac- curacies and offer the possibility of determinations of metal ions at the millimole levels. They have their applications in many chemical and biological processes. The processes involved in the formation of complex ions are basically acid-base type reactions in which the metal ion acts as an acid and the anions or molecules as the base.

Chelates in animal nutrition
Chelates ( che·late ) [kee-leyt] in animal feed are organic forms of essential trace minerals.
Animals absorb, digest and use mineral chelates better than inorganic minerals.
Chelated minerals were developed in the 1980s. Trace mineral chelates have proven to be better than inorganic minerals.
Role and source of minerals
The objective of supplementation with trace minerals is to avoid a variety of deficiency diseases. Trace minerals carry out key functions in relation to many metabolic processes, most notably as catalysts for enzymes and hormones.
Particular types of chelates
Chelates are organic molecules, normally consisting of 2 organic parts with an essential trace mineral occupying a central position and held in place by covalent bonding.
