- 9Molecular SolidsSolids held together by dispersion forces
Likely to dissolve in most solvents - 10Metallic SolidsPositive nuclei of metal atoms held together by valence electrons
- 11Network SolidsSolids held together by covalent bonds
Not likely to dissolve in most solvents - 12Ionic SolidsHeld together by electrical forces between molecules
- 13Collodial SuspensionMolecules uniformly disperses throughout the medium
Between solutions and mixtures
Between different phases - 14MiscibilityIf a solute with dissolve in a solvent
- 15SolubilityHow much a solute will dissolve in a solvent
- 16Saturation PointPoint where no more solute can be dissolved in the solvent
- 17Alloy SubstitutionReplacement of one solid atom with another to maintain general lattice shape
- 18Alloy Interstitial PlacementIntroduction of new solid atom distorts normal lattice structure
- 19Dynamic EquilibriumRate of gas escaping the liquid phase is equal to the rate of gas dissolving into the liquid phase
In a closed system - 20SurfactantsHydrophobic tail and hydrophilic head
Keep like phases near each other
Reduce surface tension of a liquid - 21MonolayersOne row of surfactants to separate phases
- 22MicellesSurfactants form circle to enclose one phase from another
- 23VesiclesBilayer of surfactants
- 24Colligative PropertiesProperties that change based on the amount of solute present
- 25Vapor Pressure ReductionNumber of available solvent molecules at the surface to escape to gas phase is reduced with the introduction of a solute
- 26Freezing Point DepressionFewer solvent molecules available to change into solid phase because of introduction of solute
- 27Boiling Point ElevationFewer solvent molecules able to reach surface and change into gas phase because of introduction of solute
- 28Osmotic PressurePressure applied to a solution to prevent the flow of solvent across a semi-permeable membrane
- 29Properties of LiquidsSurface tensions, capillary action, viscosity, vapor pressure
- 30Simple Cubic Unit CellRepeating unit form a 3D shape to represent the solid
- 31Body-Centred Cubic CellRepeating unit centred around a cell
- 32Face-Centred CubicRepeating unit centred around a cell with faces sticking out of the sides
- 33Ion-Dipole ForcesBetween ion and permanent dipole
eg, Ion dissolved in water - 34Hydrogen Bonding ForcesSlightly polar hydrogen attracted to a lone pair
eg, Water and ethanol - 35Dipole-Dipole ForcesMutual attraction of two dipoles
eg, HCl & HCl - 36Ion-Induced DipoleIon induces a dipole in another molecule then it is attracted to it
eg, Ca2+ and O2 - 37Dipole-Induced DipoleDipole induces a dipole in another molecule
eg, HCl and Cl2 - 38Dispersion ForcesShifts of electron cloud density induce momentary attractions
eg, CH4 &CH4 - 39Intermolecular Forces - Strongest to WeakestIon-Dipole
