Ionic Conductivity - an overview | ScienceDirect Topics

Ionic Conductivity Ionic conductivity is directly proportional to the concentration of the oxygen vacancy [VO⋅⋅] in the crystal in the following way: σι=2e μ [VO⋅⋅], where, μ is the mobility of the vacancies and e is the effective charge. From: Epitaxial Growth of Complex Metal Oxides, 2015

3.2.1: Hard and Soft Acid and Base Theory - Chemistry LibreTexts

The softest metal ion in the periodic table is Au + (aq). It forms stable complexes with soft bases such as phosphines and CN-, but not with hard bases such as O 2- or F-.The affinity of Au + for the soft base CN- is high, and the resulting [Au(CN) 2]- complex is so stable that gold (which is normally very difficult to oxidize) can be oxidized by oxygen in the air:

What Is Ion Exchange Resin and How Does It Work?

2017/11/28· Ion exchange is a reversible chemical reaction where dissolved ions are removed from solution and replaced with other ions of the same or similar electrical charge. Not a chemical reactant in and of itself, IX resin is instead a physical medium that facilitates ion exchange reactions. The resin itself is composed of organic polymers that form a
