Solvation shell
Solvation Shell
Solvation shell (pronunciation: /sɒlˈveɪʃən ʃɛl/) is a term used in Chemistry and Biochemistry to describe the structural arrangement of solvent molecules around a solute particle during the process of solvation.
Etymology
The term "solvation shell" is derived from the words "solvation", which refers to the interaction of solvent with dissolved molecules, and "shell", which refers to the layer of solvent that surrounds the solute in a solution.
Definition
In a solution, a solvation shell is the layer of solvent particles that surrounds each solute particle. This shell forms due to the electrostatic attraction between the solute and solvent particles. The solvation shell plays a crucial role in various physical and chemical properties of the solution, such as conductivity, viscosity, and solubility.
