Which of the following is the best example of a heterogeneous mixture?

Correct option is B

• A heterogeneous mixture consists of two or more substances that remain separate and do not mix uniformly.
• The mixture of iron chloride (a soluble compound) and iron filings (insoluble solid metal) remains visibly distinct, making it a heterogeneous mixture.

• Heterogeneous Mixture: (e.g., sand and water, oil and water).

• Homogeneous Mixture: A mixture where the components are uniformly distributed (e.g., sugar solution, salt solution).

• Examples of Heterogeneous Mixtures: Muddy water, granite, salad, blood (plasma + cells).

• Types of Heterogeneous Mixtures: Suspensions (large particles settle) and Colloids (tiny particles remain dispersed).

• Sugar in water : Homogeneous mixture; sugar dissolves completely.

• Salt in water : Homogeneous mixture; salt dissolves uniformly.

• Copper sulfate solution : Homogeneous mixture; CuSO₄ dissolves completely in water.
