Definition

1. Verb (transitive and intransitive):

   • To undergo solvation or convert into a solvate: This refers to the process where solvent molecules combine with molecules or ions of a solute, forming a loose association or compound.
   • To cause a solvation in (a substance): To bring about this process in another substance.

2. Noun (countable):

   • A compound formed by solvation: This is the product of the solvation process, consisting of solute ions or molecules surrounded by and loosely bonded to a shell of solvent molecules.

Usage Examples

• Verb:
  • The ionic compound will solvate readily in polar solvents like water.
  • The chemist sought to solvate the crystalline powder to study its properties in solution.
• Noun:
  • The stable solvate was isolated and its structure analyzed using X-ray crystallography.
  • Different solvents can form distinct solvates with the same active pharmaceutical ingredient, affecting its stability.

Advanced Usage

• Solvated Ion: An ion that is surrounded by solvent molecules. This is a common state for ions in solution.
  • In aqueous solution, sodium exists as a solvated ion, typically coordinated by several water molecules.
• Desolvate: The reverse process, where solvent molecules are removed from a solvate.
  • Upon heating, the crystal will desolvate and lose its lattice solvent.

Variants and Related Words

• Solvation (n): The process of solvent association that forms a solvate. It is the key concept from which the word "solvate" is derived.
  • The energy released during solvation helps drive the dissolution process.
• Solvated (adj): Describing a substance that has undergone solvation.
  • The solvated electron is a species of interest in radiation chemistry.

Synonyms

• For the verb (process): dissolve (in a broader sense, though "solvate" is more specific to the molecular interaction).
• For the noun (product): adduct (a more general term for a product of direct addition of molecules), solvent complex.

Related Phrases / Collocations
