The word "solvate" is pronounced /ˈsɒlveɪt/ and refers to a chemical compound consisting of a solute and a solvent. The spelling of this word is derived from the Latin word "solvō", meaning "to loosen or dissolve", and "-ate", indicating the presence of an anion. The correct spelling of this word is often confused with "solve", which means to find a solution to a problem, but the pronunciation and meaning of these two words are different.
Solvate, in chemistry, refers to the process of incorporating or dissolving a solute within a solvent, resulting in the formation of a stable solution called a solvated complex or solvated species. The solute can be a solid, liquid, or gas, while the solvent is typically a liquid, but it can also be a gas or a solid.
In solvation, the solvent molecules surround the solute particles, interacting with them through intermolecular forces such as dipole-dipole interactions, hydrogen bonding, or van der Waals forces. These interactions stabilize the solute in the solvent and prevent it from precipitating or separating. Therefore, solvation is a crucial step in many chemical processes, including dissolution, crystallization, and chemical reactions.
The solvated complex consists of the solute, now known as the solvate, and the solvent molecules that surround it. The solvent molecules are often represented using square brackets ([ ]) in chemical equations or formulas to indicate their presence. For example, if sodium chloride (NaCl) dissolves in water (H2O), the resulting solvated species can be represented as NaCl·H2O, signifying that individual water molecules are solvating each sodium chloride ion.
Furthermore, depending on the solvate's characteristics, different solvent-solute ratios and arrangements can be formed, leading to various types of solvates such as hydration (water as a solvent), solvated ionic liquids, or solvated complexes involving organic solvents.
Overall, solvation is an essential concept in chemistry as it describes the process of dissolving and stabilizing solutes within solvents to form solvated species or complexes.
A non-aqueous solution or dispersoid in which there is a combination of some kind between solvent and solute, or dispersion means and disperse phase; a similar aqueous solution or dispersoid is called a hydrate.

The word "solvate" derives from the Latin word "solvō", which means "I loosen" or "I dissolve". This Latin root is related to the process of dissolving a substance in a solvent, which is precisely what happens in a solvation reaction. The term "solvate" was coined in chemistry to describe a chemical compound or complex formed when solvent molecules surround and interact with a solute. It was first recorded in English in the late 19th century.
