Which of the following best describes what takes place during the solvation process?
A
Solute particles react chemically with solvent molecules to form a new compound.
B
Solute particles settle at the bottom of the container due to gravity.
C
Solvent molecules are converted into solute molecules through a physical change.
D
Solute particles are surrounded by solvent molecules, forming a stable solution.
Verified step by step guidance1
Understand the definition of solvation: it is the process where solvent molecules surround and interact with solute particles when a solution forms.
Recognize that solvation involves physical interactions, such as ion-dipole or dipole-dipole forces, rather than chemical reactions forming new compounds.
Eliminate options that describe chemical reactions or physical changes that do not involve the interaction between solute and solvent molecules.
Recall that solute particles do not settle at the bottom in a true solution because they are dispersed and stabilized by solvent molecules.
Conclude that the best description of solvation is that solute particles are surrounded by solvent molecules, which stabilizes the solution.
