Aniline
Aniline is an organic compound with the chemical formula C6H5NH2. It is a colorless oily liquid, although aged samples can appear yellow. Aniline is a primary aromatic amine and is an important intermediate in the production of dyes, pharmaceuticals, and other chemicals. It is highly reactive and toxic, and its exposure can be harmful to human health.
Anion
An anion is a negatively charged ion, which means it has more electrons than protons. In chemical reactions, anions are attracted to positive ions (cations) and are often found in compounds such as salts, where they balance the positive charge of the cations.
Anionic
Anionic refers to a chemical species or compound that carries a negative charge. It is derived from the Greek word "anion," which means "going down" or "negative ion." In chemistry, anions are formed when a molecule or atom gains electrons, resulting in a net negative charge. They are typically attracted to positive ions (cations) in solutions or during chemical reactions. Examples of anions include chloride (Cl-), hydroxide (OH-), and sulfate (SO42-).
