Example 1

easy
Define a homogeneous mixture and explain how it differs from a heterogeneous mixture. Give two examples of each.

Solution

  1. 1
    A homogeneous mixture has a uniform composition throughout — any sample taken from it has the same proportions of components. Examples: salt water, air.
  2. 2
    A heterogeneous mixture has a non-uniform composition — different regions have different proportions. Examples: oil and water, granite.
  3. 3
    The key distinction is uniformity at the macroscopic level: homogeneous mixtures look the same throughout, while heterogeneous mixtures show visible differences.

Answer

Homogeneous: uniform (salt water, air). Heterogeneous: non-uniform (oil/water, granite).\text{Homogeneous: uniform (salt water, air). Heterogeneous: non-uniform (oil/water, granite).}
Homogeneous mixtures are also called solutions. The particles in a homogeneous mixture are so small (molecular or ionic level) that they cannot be seen and do not settle out over time.

About Homogeneous Mixture

A mixture with a completely uniform composition throughout, where the components are evenly distributed at the molecular level and cannot be distinguished even under a.
