Practice Homogeneous Mixture in Chemistry
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
A mixture with a uniform composition throughout — the components are evenly distributed at the molecular level.
It looks the same everywhere. You can't see the separate parts, even under a microscope.
Example 1
easyDefine a homogeneous mixture and explain how it differs from a heterogeneous mixture. Give two examples of each.
Example 2
mediumIs air a homogeneous mixture or a pure substance? Justify your answer and list its major components with approximate percentages.
Example 3
mediumA student dissolves 10 g of sugar in 100 mL of water and stirs until clear. Is this a homogeneous or heterogeneous mixture? How could the student confirm this experimentally?
Example 4
hardBronze is a solid homogeneous mixture (alloy) of copper and tin. Explain why bronze is classified as a homogeneous mixture rather than a compound, even though it is a solid.
