Properties of solutions: Conductivity Solutions composed of ions are conductors of electricity A solution with a large concentration of ions is called a strong electrolyte if the solution has a small amount of ions and is composed of mostly molecular substances

What are the characteristics of a colloid solution?

A colloid solution is stable and its particles do not settle down on keeping it undisturbed. A colloid solution is translucent (i.e it allows a portion of the light through it). Particles of a dispersed phase in a colloid solution can not be seen by the naked eyes but can be seen by a powerful microscope.

What is colloidal system?

When dispersion medium is a gas, the colloidal system is called aerosol. When it is a liquid system is called solution (hydrosol for water, alcosol for alcohol, benzosol for benzene) Colloidal system is a two phase system. (2) Classification of colloids : The colloids are classified on the basis of the following criteria

What is the importance of colloids in fluid physiology?

Fluid Physiology. 7.3 Colloids. Colloids are large molecular weight (nominally MW > 30,000) substances. In normal plasma, the plasma proteins are the major colloids present. Colloids are important in capillary fluid dynamics because they are the only constituents which are effective at exerting an osmotic force across the wall of the capillaries.

What are the characteristics of colloidal emulsions?

(i) Emulsions show all the characteristic properties of colloidal solution such as Brownian movement, Tyndall effect, electrophoresis etc. (ii) These are coagulated by the addition of electrolytes containing polyvalent metal ions indicating the negative charge on the globules.
