Definition of Cation A cation refers to an ionic species that contains a positive charge. Therefore, there is a difference between cation and anion as the latter has a negative charge.

Explore the differences between cations and anions, their roles in chemical reactions, and their placement on the periodic table. Learn more now.

C. Anions are larger in size than their parent atoms. D. Anions are smaller in size than their parent atoms. E. Cations and anions both decrease in size compared to their parent ions.

Two types of ion exchange separation is possible - cation exchange and anion exchange. In anion exchange the stationary phase is positively charged whilst in cation exchange it is negatively charged.

Anion exchange membrane fuel cells (AEMFCs) have gained attention in the process of fuel cell development because they operate in alkaline environments, the redox reaction rate at the electrodes ...

Dual-ion batteries (DIBs), in which both cations and anions are involved in the electrochemical redox reaction, are one of the most promising candidates to meet the low-cost requirements of ...

Plants that remove an excess of cations over anions may cause soil acidification. The acidification potential of plants has been evaluated using solution culture techniques, but the influence of ionic ...

It can be possible to predict whether an atom will form a cation or an anion based on its position on the periodic table. Halogens always form anions, alkali metals and alkaline earth metals always ...
