At present, many ion exchangers used in industrial applications are organic compounds. Thus, this chapter focuses on the structure, synthesis, and properties of organic ion exchangers. Ion exchangers in this chapter contain all types such as resin, membrane, powder, etc....
What properties do naturally occurring metal compounds generally possess? What are the chemical properties of Group 7? What are some physical properties of nonmetals? What are the physical and chemical properties of metals? What are the properties of ionic substances? What are the general properties...
Hydrogen Bond Acceptor Properties of Ionic Liquids and Their Effect on Cellulose Solubility It is nowadays well-known that ionic liquids can dissolve cellulose. However, little systematic data has been published that shed light onto the influence ... A Stark,M Sellin,B Ondruschka,... - 《Scien...
What are the physical properties of organic compounds? Explain why water is such a good solvent for so many different solutes and describe the similarities in the dissolving process for ionic and covalent substances. Discuss the main difference when recrystallizing phenacetin vs. ac...

No equivalent complexes of Mo or W or Rh or Ir, are known . For second and third row elements , higher oxidation states are more important than those of the first row elements. For example, some compounds of second and third row elements exist in higher oxidation states which have no ...
The properties of ionic compounds shed some light on the nature of ionic bonds. Ionic solids exhibit a crystalline structure and tend to be rigid and brittle; they also tend to have high melting and boiling points, which suggests that ionic bonds are very strong. Ionic solids are also poor ...
