What is one property of skim milk indicating that it is a colloidal dispersion?
its dairy
Name the dispersion medium and dispersed phase in the white material inside an egg?
Emulsion id the dispersed phase that is in the white material of an egg. Emulsion is the mixture of two liquids.
What is a substance with particles too large to dissolve called?
A colloid is a mixture in which one substance is divided into minute particles (called colloidal particles) and dispersed throughout a second substance. The mixture they form is called a colloidal dispersion. A colloidal dispersion consists of colloids in a dispersing medium. It doesn't have to be liquid.
What is a collodial dispersion in chemistry?
An intimate mixture in which small particles are permanently dispersed throughout a solvent. Milk, for example, is a colloidal dispersion of fats, proteins, and milk sugar in water. The suspended particles are intermediate in size between visible particles and individual molecules.
Differentiate dispersion method from condensation method?
In the preparation of colloids, using the dispersion method, larger particles of the substance are broken down into much smaller parts. Using the condensation method, smaller particles are dispersed and condensed to colloidal size.
What kind of colloidal dispersion is a sol?
solid in a liquid
What is colloidal dispersion?
When particles are suspended in a viscous (thick) mixture. Lots of oatmeal based lotions are colloidal.
An aerosol dispenser contains a colloidal dispersion of?
two solids
Can you separte a colloidal dispersion using a filter paper?
yes!
What is disperstion?
Dispersion means spreading widely. eg: emulsion
What is one property of skim milk indicating that it is a colloidal dispersion?
its dairy
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 is colloidal emulsion?
An emulsion has liquid particles dispersed in a liquid medium An emulsion is a type of colloidal solution consisting of liquid(dispersed phase) mixed in another liquid(dispersing medium), so the mixture is an emulsion.A gel is a colloid of liquid(dispersed medium) mixed with solids.(eg-butter)
What is the scattering of a beam of visible light by the particles in a colloidal dispersion?
Tyndall effect
Name the dispersion medium and dispersed phase in the white material inside an egg?
Emulsion id the dispersed phase that is in the white material of an egg. Emulsion is the mixture of two liquids.
What is the dispersion of 2 liquids?
The dispersion of two (non-miscible) liquids is called an emulsion: Examples: milk, mayonnaise, hand cream
