Addition compound

Addition compound is a type of chemical compound that forms through the direct union of two or more separate compounds, without any loss of atoms. The resulting compound possesses properties that are different from those of the original compounds. Addition compounds are often formed by the combination of a molecule or ion with a coordination compound.

Formation

The formation of an addition compound involves the direct union of two or more separate compounds. This process is typically facilitated by the presence of a catalyst, which speeds up the reaction without being consumed in the process. The resulting compound is a single entity, distinct from the original compounds, and often exhibits unique properties.

Properties

Addition compounds often exhibit properties that are different from those of the original compounds. For example, they may have different melting points, boiling points, or solubility in various solvents. These differences are due to the new chemical bonds formed in the addition compound, which alter its chemical structure and, consequently, its physical and chemical properties.

Examples

A common example of an addition compound is the formation of water of hydration, where water molecules combine with a salt to form a hydrated salt. Another example is the formation of complex ions, where a central metal ion is surrounded by other ions or molecules.
