Question

4.What are homogeneous and heterogeneous mixture?

Give examples.

Define Suspension.

​

Answer 1

Answer:

Homogeneous mixture

Heterogeneous mixture

1) These are called as solutions

These are called as suspensions/colloids

2) Substances are Uniformly distributed

These substances are Unevenly distributed

3) These are not visible to the naked eye, but visible through the microscope

These are easily visible to the naked eye and also through microscope

4) The particles appear smaller in size The particles are either smaller or larger in size

5) These are pure substances

These are not pure substances

6) They represent same physical properties

They do not possess same physical properties

7) Examples include milk, gasoline, sugar solution, corn oil, fog etc

A heterogeneous mixture is simply any mixture that is not uniform in composition - it's a non-uniform mixture of smaller constituent parts. By contrast, a mixture that is uniform in composition is a homogeneous mixture

example Cereal in milk is a great example of a heterogeneous mixture. ...

Oil and water form a heterogeneous mixture.

Orange juice with pulp is a heterogeneous mixture. ...

Sandy water is a heterogeneous mixture. ...

A pepperoni pizza is a heterogeneous mixture.

Answer 2

HOMOGENEOUS MIXTURE :

• The mixture in which the composition is uniform throughout the mixture is called as heterogeneous mixture.
• Homogeneous mixture can't be seperate out physically.
• Example :- Salt water.

HETEROGENEOUS MIXTURE :

• The mixture in which the composition is not uniform is called as heterogeneous mixture.
• Heterogeneous mixture can be seperate out physically.
• Example : Oil in water.

SUSPENSION :

The heterogeneous mixture of two or more substances is called as suspension.

• In suspension, the particles are suspended.
• The particles of the suspension can seen easily.
• Example : Milk of magnesia.
