Milk is an emulsion of `W//O` type.True or False

Text Solution

AI Generated Solution

The correct Answer is:
To determine whether the statement "Milk is an emulsion of W/O type" is true or false, we can follow these steps: ### Step 1: Understand the concept of emulsions An emulsion is a mixture of two immiscible liquids, which means they do not mix well and form separate layers. There are two main types of emulsions: - **Oil in Water (O/W)**: In this type, oil droplets are dispersed in water. Water acts as the continuous phase (dispersing medium), while oil is the dispersed phase. - **Water in Oil (W/O)**: In this type, water droplets are dispersed in oil. Oil acts as the continuous phase, and water is the dispersed phase. ### Step 2: Analyze the composition of milk Milk is primarily composed of water and fat. The fat in milk exists in the form of tiny globules that are dispersed throughout the water. ### Step 3: Identify the type of emulsion in milk In milk: - The **dispersing medium** is water. - The **dispersed phase** is fat (oil). Since the fat (oil) is dispersed in water, this indicates that milk is an **Oil in Water (O/W)** emulsion, not a Water in Oil (W/O) emulsion. ### Step 4: Conclusion Given that milk is an emulsion of the O/W type, the statement "Milk is an emulsion of W/O type" is **False**. ### Final Answer: **False** ---

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.
