Question

What are mixtures? Describe the types of mixtures with examples.

Answer 1

• A mixture is formed when atoms or molecules of the same or different particles combine with each other physically.
• For example - Air is a mixture of gases like Carbon dioxide$\left({\mathrm{CO}}_2\right)$, Nitrogen$\left({\mathrm{N}}_2\right)$, Oxygen$\left({\mathrm{O}}_2\right)$, etc; dust, Water vapors$\left({\mathrm{H}}_2\mathrm{O}\right)$
• Mixtures of majorly of two types - Homogeneous and Heterogeneous mixtures.
• Homogeneous mixtures are those mixtures that have uniform composition and their constituents cannot be seen by naked eyes. For example - A mixture of salt and water, etc.
• Heterogeneous mixtures are those mixtures that do not have uniform composition and their constituents can be seen from naked eyes. For example - a mixture of sand and water, a mixture of iron filings and sand, etc.
