Example 1

easy
Define a mixture and explain how it differs from a pure substance. Give two examples.

Solution

  1. 1
    A mixture is a combination of two or more substances that are physically combined but not chemically bonded.
  2. 2
    Unlike a pure substance, a mixture has variable composition — the proportions of components can change.
  3. 3
    Examples: salt water (varying amounts of salt), air (varying amounts of water vapor). Both can be separated by physical methods.

Answer

Mixture: variable composition, physically separable (e.g., salt water, air)\text{Mixture: variable composition, physically separable (e.g., salt water, air)}
Mixtures retain the properties of their individual components, while pure substances have fixed, characteristic properties. This distinction is fundamental to classifying all forms of matter.

About Mixture

A physical combination of two or more substances that are not chemically bonded, retain their individual properties, exist in variable proportions, and can be separated.
