Understanding the Statements
Statement A discusses the separation of constituents in mixtures, while Statement B classifies milk as a pure substance. Let’s break down each statement for clarity.
Statement A: Separation of Constituents
- Mixtures are classified into two types: homogeneous and heterogeneous.
- Homogeneous Mixtures: These are uniform in composition, meaning they appear the same throughout. Examples include solutions like saltwater.
- Heterogeneous Mixtures: These consist of visibly different substances or phases. Examples include salad or sand and iron filings.
- Separation: It is generally easier to separate components of a heterogeneous mixture because the distinct substances can be easily seen and physically separated. In contrast, homogeneous mixtures often require complex methods such as distillation or chromatography for separation.
Statement B: Milk as a Pure Substance
- A pure substance has a constant composition and distinct chemical properties.
- Milk: Although milk may seem like a uniform substance, it is not a pure substance. It is an emulsion, meaning it contains water, fat, proteins, lactose, and minerals, making it a complex mixture rather than a single pure substance.
Conclusion: Evaluation of Both Statements
- Statement A is Correct: It correctly identifies the ease of separation being greater in heterogeneous mixtures.
- Statement B is Incorrect: Milk cannot be classified as a pure substance due to its mixture of various components.
Therefore, the correct answer is option 'C': Neither Statement A nor B is entirely correct.
