Current Question (ID: 18462)

Question:

$\text{Correct statement about emulsion is:}$

Options:

1. $\text{The dispersed phase and dispersion medium are liquids.}$
2. $\text{The dispersed phase and dispersion medium are solids.}$
3. $\text{The dispersed phase and dispersion medium are gases.}$
4. $\text{The dispersed phase are solids and dispersion medium are liquids.}$

Solution:

$\text{HINT: Emulsion is liquid in liquid type colloidal solution.}$ $\text{Explanation:}$ $\text{The colloidal solution in which both the dispersed phase and dispersion medium are liquids is called an emulsion.}$ $\text{There are two types of emulsions:}$ $\text{(a) Oil in water type: Here, oil is the dispersed phase while water is the dispersion medium. For example: milk, vanishing cream, etc.}$ $\text{(b) Water in oil type: Here, water is the dispersed phase while oil is the dispersion medium. For example: cold cream, butter, etc.}$
