A homogeneous mixture or solution consists of _____.

Fed [463]

Answer: Option (C) is the correct answer.

Explanation:

A mixture in which the components are evenly distributed or the components are present in same proportion throughout the mixture is known as a homogeneous mixture or solution.

As a result, there exists only one phase in the mixture. The components of mixture can be in solid, liquid or gaseous form.

For example, when sodium chloride (solid phase) is added in water (liquid phase) then it completely dissolve in it. Thus, there will be no boundary between the solute and solvent. Hence, it forms a homogeneous solution.

Therefore, we can conclude that a homogeneous mixture or solution consists of substances in more than one phase.
