Hint: We have to know that milk is a complex chemical substance which contains fat, protein and some other minerals which present in a colloidal state. And the molecular formula of milk is . The milk contains fat, water and solids in the form of carbohydrates and proteins. These components are mixed irrationally. Therefore, milk is not a pure substance. The main compounds present in the milk are casein and lactose.
Complete answer:
We need to remember that the milk is not an example of a solution, because the milk contains more than one phase which is suspended in it. That is, solid phase and liquid phase. Therefore, the milk is suspended and it is not a solution. Hence, the option (1) is incorrect.
The milk is an example of a homogeneous mixture. Because, the homogeneous mixture has a uniform composition throughout the mixture. And the dissolved materials should be present in the same amount and the homogeneous mixture is a gaseous, liquid or solid mixture. The components present in the milk at the same proportions throughout the sample. Thus, the milk is a homogeneous mixture. Hence, option (2) is correct.
In a heterogeneous mixture, the components are not in the same proportions. Hence, the option (3) is incorrect.
So, the correct answer is “Option 2”.
Note:
We must know that the mixture contains one or more pure substances in different compositions. And these are mainly divided into two types and that is, homogeneous mixture and heterogeneous mixture. In the case of homogeneous mixture, the components are present in the same compositions. But in the case of heterogeneous mixture, the components are not in uniform proportions.
