Question

difference between homogeneous and hetrogenous mixture with examples ​

Answer 1

• Mixtures are formed when two or more substances (elements or compounds) mix together without participating in a chemical change. The substances need not necessarily mix in a definite ratio to form a mixture.

• Mixtures can be of two types;-

(i)Homogenous Mixture

(ii)Heterogeneous Mixture

• Difference between Homogenous Mixture & Heterogeneous Mixture;-
• Homogenous Mixture;-

1. Particles are distributed uniformly
2. We can’t judge a homogeneous mixture by just seeing it
3. Homogeneous mixtures are also called solutions
4. Uniform composition

• Example: rainwater, vinegar, etc.                                                                      

• Heterogeneous Mixture;-

1. Particles are distributed non uniformly
2. We can judge a heterogeneous mixture by just seeing it
3. Non-uniform composition

• Example: seawater, pizza, etc.

Answer 2

Answer:

Homogeneous Mixture: A homogeneous mixture has the same uniform appearance and composition throughout.

    Many homogeneous mixtures are commonly referred to as solutions

Eg: Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances.

Heterogeneous Mixture: A heterogeneous mixture consists of visibly different substances or phases.

   A heterogeneous mixture has components in which proportions vary throughout the sample.

Eg: Rocks in the sand at the beach are a heterogeneous mixture.
