Does anyone know examples of a colloid or suspension in chemistry?
Q. It has to do with chemistry, not cars.

A. colloid = any system involving two phases where one phase is dispersed in another... the dispersed phase is usually less than 1micrometre in particle size...eg... mayyonaise is an oil/water suspension; photographic film is a colloidal suspension of silver halide

A. 1. Chemistry. 1. A system in which finely divided particles, which are approximately 10 to 10,000 angstroms in size, are dispersed within a continuous medium in a manner that prevents them from being filtered easily or settled rapidly. 2. The particulate matter so dispersed. 2. Physiology. The gelatinous product of the thyroid gland, consisting mainly of thyroglobulin, which serves as the precursor and storage form of thyroid hormone. 3. Pathology. Gelatinous material resulting from colloid degeneration in diseased tissue. Particles (the disperse phase) suspended in a second medium (the dispersion medium); can be solid, liquid, or gas suspended in a solid, liquid, or gas. Examples of gas-in-liquid colloids are beaten egg-whi [cont.]

A. Lyophilic colloid - The colloidal particles are more attracted to the dispersing medium than to each other. The effect: This prevents the colloidal particles from coagulating (clumping) together to form large particles which will settle out.

A. a suspension is a liquid and a solid in which the solid is in suspension in the liquid. a good example is something like dirt and water. the dirt is a solid and it is suspended in the water. a colloid is a misture of two liquids. an example is water and alcohol. the alcohol is slightly soluble in water and so they make a colloid.

A. Colloids and suspension : It is possible to prepare a solution where the particles fo the substance dispersed in the liquid are intermediate in size between those of solute particles and the particles of a suspension. Such a solution is called a colloidal solution. A suspension is where the substance does not dissolve in the solvent. A colloid is when a solution of sulphur dioxide is added to a solution of hydrogen sulphide, sulphur is formed. Milk is a colloid. Suspension example is table salt in oil, pebbles in water. -Colloids : colloids are mixtures with particle sizes that consist of clumps of molecules.

A. A solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is dissolved in another substance, known as a solvent. A common example is a solid, such as salt or sugar, dissolved in water, a liquid. Gases may dissolve in liquids, for example, carbon dioxide or oxygen in water. Liquids may dissolve in other liquids. A suspension is a heterogenous fluid containing solid particles that are sufficiently large for sedimentation. An example of a suspension would be sand in water. Unlike colloids, suspensions will eventually settle. A colloid is a type of mechanical mixture where one substance is dispersed evenly throughout another.

A. A suspension is particles dispersed in a liquid, which will remain stable for a short time, but will separate on standing. The particles can be filtered out. A colloid is very fine particles dispersed in a liquid in such a way that they are stable and do not settle out, nor can they easily be filtered out. Suspension examples: Milk of magnesia (yuk), calamine lotion - think of anything powdery in a liquid that you have to shake before use. Colloid examples: White paint (titanium dioxide particles); Milk.

A. Solution is a molecular mix of components. Example is salt or vinegar in water. Suspension (or dispersion) is the presence of solute (colloidal particles) into a solvant. Milk is an example. Mayonnaise is another example (colloids are oil droplets here). Colloidal particles do not go under gravity and undergo thermal agitation. Another kind of suspension is smoke in the air.

A. there are 2 main classification: 1.lyophilic colloids, e.g proteins ,starch and rubber these are much stable and are also called as reversible colloids. these substances have strong interactions with the dispersion medium. 2.lyophobic colloids, e.g.arsenic sulphide,ferric hydroxide these are much less stable and are called as irreversible colloids these are sparingly soluble and dont pass into colloidal state readily.

A. Metal colloid like gold sols, etc. are positive colloids. Blood and muddy water are negatively charged colloids. Charge is accuired by colloids due to several reasons: 1. Selective adsorption of cations or anionsn on the surface of colloidal particles. 2.Ionization of molecules on the surface of colloidal particle. 3. electron capture, etc.

A solution shows no light scattering at all. A colloid is like a solution in that there is the same kind of stability...except that what is in dispersion is something like a protein, which likes water ok, except that the colloid shows the Tyndall effect, because the particles in suspension are about the same size as the wavelengths of light you are using to observe the effect; solutions do not have this, since both the water and solute are molecules and too small to scatter light.

Asked by Jenny - Fri Sep 25 00:23:45 2009 - - 2 Answers - 0 Comments
A. The quick and easy answer is the particle size dispersed in the medium and the appearance. A colloid has particles sizes that are between a homogeneous and a heterogeneous mixture. The appearance of the colloid determines whether the colloid is considered homogeneous or heterogeneous. Mayonnaise is has a homogeneous appearance. Milk can have a homogeneous appearance or, if the butterfat particles have not been broken down, can appear heterogeneous. (milk is a colloidal mixture of liquid butter fat suspended in a water based liquid)
