Emulsion surface chemistry11/29/2023 (v) Digestion of fats in intestine is through emulsification. (iv) Milk, which is an important constituent of our diet an emulsion of fat in water. (ii) In medicine (Emulsion water-in-oil type) This process is also known as demulsification. (a) Effect of concentration and temperature on. (iv) Emulsions can be converted into two separate liquids by heating, centrifuging, freezing etc. (c) Study of the role of emulsifying agents in stabilizing the emulsion of different oils. However, the size is smaller than the particles in suspensioins. ![]() (iii) The size of the dispersed particles in emulsions in larger than those in the sols. (ii) These are coagulated by the addition of electrolytes containing polyvalent metal ions indicating the negative charge on the globules. the surface of your pcb: Step 1: Etch your ORIGINAL BUNGARD PCB as usual. (i) Emulsions show all the characteristic properties of colloidal solution such as Brownian movement, Tyndall effect, electrophoresis etc. (Chemistry) a material sensitive to light that is used in industrial processes. Butterand cold creamare typical examples of this types of emulsions. These emulsion are also termed oil emulsions. (ii) Water-in-oil emulsion (W/O) : The emulsion in which water forms the dispersed phase, and the oil acts as the dispersion medium is called a water-in-oil emulsion. propagating chains of free radicals acquire surface-active properties. In milk liquid fat globules are dispersed in water. The full mechanism of emulsion polymerization is still not completely worked out. Milk is an example of the oil-in-water type of emulsion. (i) Oil-in-water emulsions (O/W) : The emulsion in which oil is present as the dispersed phase and water as the dispersion medium (continuous phase) is called an oil-in-water emulsion. (1) Types of Emulsion : Depending upon the nature of the dispersed phase, the emulsions are classified as ![]() Emulsion resemble lyophobic sols in some properties. ![]() The size of the emulsified globules is generally of the order of \ m. “Emulsion are the colloidal solutions in which both the dispersed phase and the dispersion medium are liquids.”Ī good example of an emulsion is milk in which fat globules are dispersed in water. “The colloidal systems in which fine droplets of one liquid are dispersed in another liquid are called emulsions the two liquids otherwise being mutually immiscible.” or
