Colloidal Dispersions || Classification of Dispersed System | L-1, Unit-1 | Physical Pharmaceutics 2

Carewell pharma2 minutes read

The channel will cover topics related to physical power for b pharmacy 4th semester, including collar disposal and Dennis classification. These topics involve mixing solid and solvent to create solutions categorized based on particle size and dispersion, with molecules crossing semipermeable membranes easily due to their small size.

Insights

  • **Colloidal Solutions:** The channel will delve into topics like collar disposal and Dennis classification, focusing on colloidal solutions with particles ranging from one nanometer to a thousand nanometers. This size range distinguishes colloidal solutions from bacteria, which are smaller and require a microscope for viewing.
  • **Dispersion and Classification:** The classification of particles based on size, dispersion medium, and dispersion phase is crucial in understanding physical states like solid, liquid, and gas. Molecular dispersion and course dispersion are key categories, with molecules being imperceptible in an electron microscope but able to cross semipermeable membranes due to their size, illustrating the importance of understanding particle behavior in different mediums.
