The Dissolution Process
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Dissolving a solute means replacing solute-solute and solvent-solvent attractions with new solute-solvent attractions, favorable only when those can compete.
Show
Table salt dissolves in water because strong ion-dipole attractions to Na+ and Cl- compete successfully against the ionic lattice.
Watch for
Dissolution is a competition between old and new attractions, not passive mixing — some pairs never form a stable solution.
