solvation
Noun: 1. A chemical process of association or combination: Specifically, solvation is the process in which molecules or ions of a solute interact with and become surrounded by molecules of a solvent, forming a loose chemical association or compound (a solvate complex). This process is fundamental to dissolution.
Solvation describes the critical interaction that occurs when a substance dissolves. It is the key step that stabilizes solute particles in a solution. * The solvation of sodium and chloride ions by water molecules is why table salt dissolves so readily. * The energy released during solvation helps overcome the lattice energy of the ionic crystal. * Researchers studied the solvation shell, the layer of solvent molecules surrounding each ion.
- Specific Solvents: The term is often modified to specify the solvent involved.
- Aquation or hydration refers specifically to solvation by water.
- The solvation of the polymer in the organic solvent was incomplete.
- Solvation Energy: This is a key thermodynamic quantity representing the energy change associated with the solvation process.
- A high negative solvation energy indicates a very favorable dissolving process.
- Solvate (noun): The loose compound or complex formed between the solute and solvent molecules.
- The crystal structure revealed a hexahydrate solvate.
- Solvate (verb): To undergo or subject to solvation.
- The ion is solvated by several water molecules.
- Desolvation (noun): The reverse process, where solvent molecules are removed from a solvated ion or molecule.
- Hydration (noun): Solvation specifically by water molecules.
- Dissolution (though this is a broader process that includes solvation)
- Hydration (when the solvent is water)
- Precipitation
- Crystallization
- Desolvation
- Solvation Shell: The sphere of solvent molecules directly surrounding a dissolved solute particle.
- Dielectric Constant: A solvent property that significantly influences its solvation power, especially for ionic solutes.
- Solubility: The extent to which a solute undergoes solvation and dissolution in a given solvent.
-
a chemical process in which solvent molecules and molecules or ions of the solute combine to form a compound
