Essential Principles of Physical Pharmacy and Chemistry

Raoult's Law and Distribution Law

• Raoult's Law: Describes the relationship between vapor pressure and the mole fraction of a solvent.
• Distribution Law: Describes the distribution of a solute between two immiscible liquids.

Complexation Classification and Measurement

• Classification: Complexes can be classified as coordination, molecular, or inclusion complexes.
• Methods of measurement: Include spectrophotometry, chromatography, and titration.

HLB and Sorensen pH Scales

• HLB Scale: Measures the hydrophile-lipophile balance of a surfactant.
• Sorensen pH Scale: Measures the pH of a solution using a logarithmic scale.

Aerosols and Inhalers

• Aerosol: A suspension of fine solid or liquid particles in a gas.
• Inhaler: A device used to deliver medication to the lungs.

CST and Optical Activity

• CST (Critical Solution Temperature): The temperature above which a solution becomes miscible.
• Optical activity: The ability of a substance to rotate plane-polarized light.

Buffer and Isotonic Solutions

• Buffer solution: A solution that resists changes in pH.
• Isotonic solution: A solution that has the same osmotic pressure as blood.

Methods of Measuring Surface Tension

• Methods include: Capillary rise, pendant drop, and Wilhelmy plate.

CMC and Sublimation Critical Point

• CMC (Critical Micelle Concentration): The concentration above which surfactants form micelles.
• Sublimation critical point: The temperature and pressure above which a substance sublimes.

Vapor Pressure and Latent Heat

• Vapor pressure: The pressure exerted by a vapor in equilibrium with its liquid.
• Latent heat: The heat required to change the state of a substance without changing its temperature.

Liquid Crystals and the Glassy State

• Liquid crystal: A state of matter that exhibits properties of both liquids and crystals.
• Glassy state: A state of matter that is amorphous and rigid.

Crystalline and Amorphous Solids

• Crystalline solid: A solid with a regular, three-dimensional arrangement of atoms.
• Amorphous solid: A solid with a random arrangement of atoms.

Surface Free Energy and Buffer Capacity

• Surface free energy: The energy associated with the surface of a substance.
• Buffer capacity: The ability of a buffer solution to resist changes in pH.

Protein Binding and Detergency

• Protein binding: The binding of a substance to a protein.
• Detergency: The ability of a surfactant to remove dirt and grime.

Association and Solubilization

• Association: The formation of a complex between two or more substances.
• Solubilization: The process of dissolving a substance in a solvent.
