Some Important Definition 1) Coordination Entity: Central atom/ion (metal) to which a fixed number of other atoms or groups are attached (ligand). For example, [CoCl 3 (NH 3) 3] is a coordination entity in which the cobalt ion is surrounded by three ammonia molecules and three chloride … Counterions are the mobile ions in ion exchange polymers and colloids. Ion-exchange resins are polymers with a net negative or positive charge. Cation-exchange resins consist of an anionic polymer with countercations, typically Na (sodium). The resin has a higher affinity for highly charged countercations, for example … See more In chemistry, a counterion (sometimes written as "counter ion", pronounced as such) is the ion that accompanies an ionic species in order to maintain electric neutrality. In table salt (NaCl, also known as sodium chloride) … See more In order to achieve high ionic conductivity, electrochemical measurements are conducted in the presence of excess electrolyte. In water the electrolyte is often a simple salt such as potassium chloride.
