Study Notes
Dissolving Ionic Compounds
- Water molecules reorient themselves around ions, creating stronger attractions than the ionic bonds holding the ions together.
- Hydration is the process of surrounding ions with water molecules.
- Dissociation is the separation of individual ions from an ionic compound as it dissolves in water.
- Example: NaCl(s) → Na+(aq) + Cl−(aq)
Dissolving Molecular Compounds
- Miscible: substances that mix to form a solution (e.g., glucose and water).
- Immiscible: substances that do not mix to form a solution (e.g., oil and water).
"Likes Dissolve Likes" Principle
- Polar solutes dissolve in polar solvents.
- Nonpolar solutes dissolve in nonpolar solvents.
Dissolving Process
- The solvent makes space for the solute, causing them to separate.
- Forces of attraction between solute and solvent particles cause them to move closer together.
