Study Notes

Colloidal Dispersion Systems

  • The main characteristic of colloidal dispersion systems is that they consist of particles with diameters between 1-100 nanometers, which are dispersed in a medium, such as a gas, liquid, or solid.

Destabilization of Colloidal Dispersion Systems

  • The process that leads to the destabilization of colloidal dispersion systems is aggregation, which occurs when the particles aggregate or come together to form larger clusters, losing their dispersed state.

Effect of 'Salting Out' on Colloidal Dispersion Systems

  • The effect of 'salting out' on colloidal dispersion systems is that it causes destabilization, as high concentrations of electrolytes (salts) in the medium disrupt the balance of repulsive and attractive forces between particles, leading to aggregation and precipitation.

Test your knowledge on dispersal systems, including the classification, properties, and specific characteristics of colloidal dispersions and high molecular mass compounds. Explore their stability, coagulation, and salting out phenomena.
