select correct statement. A.water in oil emulsion are more viscous than the aqueous emulsion B.electrical conductance of aqueous emulsions is less than that of oil emulsions C.demulsification can be done with soap or detergent D.an emulsion can be diluted with H20 then it is oil in water (w/ 0) type.

Which of the following given statements is/are correct? (a) cold cream is an example of (W/O) type emulsions, (b)electrical conductance of aqueous emulsions is less than that of oil emulsions (c) emulsions cannot be broken into constituent liquids by heating or freezing (d) an emulsion can be diluted with water, then it forms (O/W) type emulsion

Some of the properties of emulsions are: I. Emulsions scatter light and thus exhibit Tyndall Effect II. Oily emulsions are more viscous than aqueous emulsions III. Electrical conductance of aqueous emulsions is higher than that of oily emulsions and increases on the addition of electrolyte. Select the correct properties:

which of the following statement is not true about the oil - in - water type emulsion ?

Give one test to distinguish whether the given emulsion is oil-in-water-type emulsion.

Emulsions are normally prepared by shaking the two components together vigorously although some kind of emulsifiying agent usually has to added to stabilize the product. This emulsifying agent amy be a soap or other sufactant (surface active) sepcies or a lyophilic sol that forms a protective film around the dispersed phase. Emulsion broadly classified into two types: (i) Oil in water emulsions (O/W): Oil acts as dispersed phase and water acts as dispersion medium. (ii). Water in oil emulsion (W/O): Water acts as dispersed phase and oil acts as dispersion medium Due test, dilution test may be emplyoyed for identification of emulsions. Q. Read two statment s: (1) milk is an example of oil in water (O/w) type emulsion (2) cold cream is an example of water in oil (W/O) type emulsion

Assertion(A): Small quanity of soap is used to prepare a stable emulsion. Reason(R): Soap lowers the interfacial tension between oil and water.
