Complex ions are charged species consisting of a central metal atom or ion bonded to surrounding molecules or anions, known as ligands, through coordinate covalent bonds. These structures play a crucial role in various chemical processes, influencing properties like solubility, color, and reactivity in both natural and industrial settings.

Properties of complex ions

Solubility is the ability of a substance to dissolve in a solvent, forming a homogeneous mixture at a specific temperature and pressure. It is influenced by factors such as temperature, pressure, and the nature of the solute and solvent, and is crucial in fields ranging from chemistry to pharmacology.
