Study Notes
Physical Pharmacy
- Physical pharmacy applies physical and chemical principles and laws to develop dosage forms and drug delivery systems.
Forces of Attraction
- Atoms are the basic units of matter, consisting of protons, neutrons, and electrons.
- Intermolecular forces include:
- Ionic Bond: transfer of electrons
- Covalent Bond: sharing of electrons
- Polar (unequal sharing)
- Nonpolar (equal sharing)
Physical Properties of Systems
- Additive Property: depends on the sum of individual properties of components
- Constitutive Property: depends on the type and arrangement of components
- Colligative Property: depends on the number of components
- Types of Properties:
- Extensive/Extrinsic: depends on the size or amount of material (e.g., mass, volume, area)
- Intensive/Intrinsic: does not depend on the size or amount of material (e.g., density, melting point, boiling point)
States of Matter
- Solid: fixed shape, nearly incompressible, strong intermolecular forces, little kinetic energy
- Liquid: takes shape of container, incompressible, some kinetic energy
- Gas: fills available space, compressible, rapid motion, weak intermolecular forces
- Plasma (Mesophase/Liquid Crystal): intermediate phase between solid and liquid
- Types: Smectic, Nematic, Cholesteric
- Supercritical Fluid State: between liquid and gas
- Liquefaction of Gases: critical temperature (Tc) and critical pressure (Pc) determine liquefaction
Solids
- Crystalline Solids: have definite geometric forms, 6 common crystalline structures (cubic, tetragonal, etc.)
- Amorphous Solids (Glasses or Supercooled Liquids): non-crystalline, no definite order, no sharp melting point
- Clathrates: trap a molecule within its lattice, lack reproducibility
- Solvates: have a solvent within the lattice (e.g., hydrates)
- Polymorphs: have different physical properties, including melting points and solubilities
