Why is it important to remove the electrolytes in colloidal system?
Generally electrolytes' ions bind to the surface and damage the double electrostatic layer of colloidal particles. This greatly reduces stability of a colloidal system, since electrostatic repulsion is the main force keeping those colloidal particles apart.
Why do most colloids have electrical charges?
One of the most important properties of colloidal solutions is that colloidal particles posses a definite type of electrical charge. In a particular colloidal solution, all the colloidal particles carry the same type of charge, while the dispersion medium has an equal but opposite charge. Thus, the charge on colloidal particles is balanced by that of the dispersion medium and the colloidal solution as a whole is electrically neutral.
What is difference between sol and gel and emulsion?
Sol state is a liquid state .The colloidal particles repel each other. Gel state is more jellylike. The colloidal particles attract each other. emulsion are colloidal system in which both dispersed phase and dispersed medium are in liquid state .
What are colloidal salts?
Colloids are dispersed particles with a diameter of 1-1000 nm.
In a colloid the particles are?
Colloids have moderately sized particles. (small enough to stay in suspension)

What is colloidal particles spreading throughout a suspension?
Dispersed particles

How can distinguish a colloid from a suspension?
the colloidal particle show tyndal effect while suspended particles donot. Colloidal particles donot settle down but the suspended particles get settledown.
What are the colloidal mixture?
A colloidal mixture contain particles with dimension under 1 000 nm.
What is colloidal dispersion?
When particles are suspended in a viscous (thick) mixture. Lots of oatmeal based lotions are colloidal.
What do you mean in electrical charge effect of colloids?
A dispersed colloidal particle can absorb electrically charged particles (either positive or negative) on its surface. Colloidal particles of a given kind will all have the same electric charge. Because of this , the dispersed colloidal particles repel each other.
The colloidal particles in a colloid form the what?
dispersed phase
What is metal in water?
If you are referring to any metal particles suspended in water I believe the term you are looking for is Colloidal. For example.... Colloidal Silver is silver particles suspended in water.
Why colloidal gold turns to red?
Colloidal gold turns to red due to the red blood cells of the gold particles.
What are some characteristics of colloidal particles?
