Question

How can mixtures be classified?

Answer 1

Hint: When two or more substances are mixed together, the result is called a mixture.
Mixtures can be classified into two main categories: homogeneous and heterogeneous.
Examples: Smoke and fog (Smog)
Dirt and water (Mud)
Sand, water and gravel (Cement)
Water and salt (Sea water)

Complete step by step answer:
A mixture is a material made up of two or more different substances which are physically combined.
Mixtures can be classified on the basis of particle size into three different types: solutions, suspensions and colloids.
HOMOGENEOUS MIXTURE:
A homogeneous mixture is one in which the composition of its constituents are uniformly mixed throughout.
A homogeneous mixture in which one substance, the solute, dissolves completely in another substance, the solvent, may also be called a solution.
In a homogeneous solution, the particles of solute are spread evenly among the solvent particles and the extremely small particles of solute cannot be separated from the solvent by filtration through filter paper
examples of homogeneous mixtures include sugar water .
HETEROGENEOUS MIXTURE:
A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture
Example: Vegetable soup is a heterogeneous mixture. Any given spoonful of soup will contain varying amounts of the different vegetables and other components of the soup.
Homogeneous mixture is one in which all components are in a single phase, while a heterogeneous mixture contains components in different phases.
A heterogeneous mixture varies in its composition.

Note: Heterogeneous mixture is a nonuniform mixture in which the components separate and the composition varies and can be separated through physical processes.
You can find many examples of heterogeneous mixtures in solid, liquid and gaseous form throughout nature .Some more examples of heterogeneous mixtures include oil and water .
