Question

What are the characteristics of a mixture? Explain using examples.

Answer 1

Characteristics of a mixture:

• It is formed by the physical combination of two or more substances. Example- Air is a mixture containing various gases and dust particles. The components of air are just mixed with each other, not combining chemically.
• Composition of the substances can vary. Example- In a mixture of water and sand, we can vary the amount of sand or water as per the need. But in all the cases, we will get a mixture.
• It shows the properties of its constitutents. Example- In a mixture of iron filings and sulphur powder, magnetic property of iron is retained.
• The formation of mixture is not a new substance since the chemical properties are not changed. Example- A mixture of water and sugar is not considered to be a new substance, since the components are just mixed without undergoing any reaction.
