A cation refers to an atom or a group of atoms that bear one or multiple positive electric charges. An anion refers to an atom or a group of atoms that bear one or multiple negative electric charges.

Cations can be identified with flame tests or precipitate tests using sodium hydroxide and ammonia solutions. Anions (halide, sulfate, and carbonate ions) can be identified using precipitate tests or ...

Chemists have found that the all-cis isomer of hexafluorocyclohexane, a molecule that made headlines last year for being the most polar aliphatic compound known, is capable of binding both cations and ...

Boron cluster chemistry occupies a unique niche in modern chemical science, bridging fundamental inorganic chemistry with practical materials applications. Central to this field is the study of ...

Charged particles in aqueous solutions are always surrounded by a shell of water molecules. However, much is still unknown about the nature of this so-called hydration shell. Using terahertz ...

A “cooperative” behavior between complex mixtures in battery electrolytes could provide a new blueprint for future battery design, enabling the wider development of multivalent batteries. In a new ...

Water is essential for all chemistry and life, yet understanding how it interacts with dissolved ions—such as sodium and magnesium—has long been a major scientific challenge.
