Practice Heterogeneous Mixture in Chemistry
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
A mixture in which the composition is not uniform throughout, with visibly or microscopically distinct regions that have different compositions and properties.
Different parts look or behave differently. One spoonful is not the same as another.
Example 1
easyDefine a heterogeneous mixture and explain how to recognize one. Provide three examples.
Example 2
mediumClassify the following as homogeneous or heterogeneous and justify: (a) Italian salad dressing (oil and vinegar layers), (b) milk under a microscope (tiny fat droplets in water), (c) filtered apple juice.
Example 3
mediumExplain why oil and water form a heterogeneous mixture rather than a homogeneous one, using the concept of polarity.
Example 4
hardBlood is often described as a heterogeneous mixture. Identify at least three distinct components of blood and explain why centrifugation can separate them.
