Answer

Is Milk a Mixture or a Pure Substance?
Milk is considered a mixture rather than a pure substance due to its composition. It is made up of various components that are not chemically bonded together, making it a heterogeneous mixture.

Components of Milk
1. Water: The main component of milk is water, which makes up about 87% of its content.
2. Fats: Milk contains fats in the form of triglycerides, which contribute to its creamy texture.
3. Proteins: Milk is a good source of proteins such as casein and whey, which are essential for growth and repair.
4. Lactose: Milk also contains lactose, a type of sugar that gives it a slightly sweet taste.
5. Minerals and Vitamins: Milk is rich in various minerals like calcium, phosphorus, and vitamins like vitamin D.

Homogeneity of Milk
Despite being a mixture, milk appears homogenous to the naked eye. This is because its components are evenly distributed throughout the liquid. However, upon closer inspection, one can observe that milk is indeed a mixture due to its varied components.

Separation of Milk
If left undisturbed, milk will eventually separate into different layers based on the density of its components. For example, cream will rise to the top due to its higher fat content, while whey and water will settle at the bottom.

Conclusion
In conclusion, milk is a mixture due to its diverse composition of water, fats, proteins, lactose, minerals, and vitamins. While it may appear homogenous, it can be separated into its individual components, further solidifying its classification as a mixture rather than a pure substance.
