. Why is milk regarded as a mixture and not as a pure substance

Best Answer

Explanation:

• A pure substance, as we know, is an element/a compound, whereas a mixture is the result of the interaction of two and more substances.
• Milk is an unnaturally mixed mixture of water, fat, and solids since it comes from cows (in the form of milk protein and carbs).
• So, milk is a mixture rather than a single substance, with lactose and casein as the primary components.
• It's also a colloidal combination (that is when one substance of microscopically distributed insoluble or soluble particles is suspended in another).
• As a result, milk is seen as a mixture rather than a single entity.

Final Answer:

Milk consists of fatty acids, proteins, and minerals. So, it is a colloidal mixture.
