Solvation Strong Electrolyte Non- Electrolyte solute exists as ions only - + salt - + sugar solute exists as molecules only - + acetic acid Weak Electrolyte solute exists as ions and molecules DISSOCIATIONIONIZATION View animation online.animation
Solvation DISSOCIATIONIONIZATION View animation online.animation The seperation of ions from a compound during solution. (Ionic Compounds) Ex. Sodium chloride, NaCl The formation of ions from solute molecules by the action of a solvent. (Covalnetly bonded molecules) Ex. acetic acid, HCH 3 COO
