👉 Arachic is a term used in the scientific field of organic chemistry, specifically referring to the concept of chemical reactions that occur when an element with positive charge on one side of the atom (the cation) and a negative charge on the other (the anion) comes into contact with another element with a similar charge. This reaction results in the formation of ions or compounds, which can then be used for various purposes such as catalysis, ion exchange, and synthesis.
