14 - Analytical and Coordinate Chemistry

Abstract

This chapter presents concepts of analytical chemistry. Acid-base chemistry is important for pulping and bleaching operations. Redox reactions are important to understand bleaching, corrosion, and ion-specific electrodes. Coordinate chemistry is central to alum and wet end chemistry, and involves many principles of analytical chemistry. For more detail on these concepts, an introductory text on quantitative analysis or analytical chemistry should be consulted. In addition coordinate chemistry explains the behavior of alum in aqueous solutions. Coordinate chemistry involves the formation of complexes when two atoms share an electron pair. One species makes the donation and the second species accepts the electron pair. Coordinate covalent bonds are formed when one atom donates both electrons of the electron pair; with other covalent bonds each atom donates one electron to the pair. Applications of coordinate chemistry will undoubtedly receive much wider recognition in the future by the pulp and paper industry.
