Question

Explain homogeneous and heterogeneous ​

Answer 1

Answer:

homogeneous mixture is a solid, liquid or gaseous mixture that has the same proportions of its components throughout any given sample. Conversely, a heterogeneous mixture has components in which proportions vary throughout the sample. "Homogeneous" and "heterogeneous" are not absolute terms, but are dependent on context and the size of the sample. In chemistry, if the volume of a homogeneous suspension is divided in half, the same amount of material is suspended in both halves of the substance. An example of a homogeneous mixture is air.

In physical chemistry and materials science this refers to substances and mixtures which are in a single phase. This is in contrast to a substance that is heterogeneous.

Answer 2

Homogeneous mixture:

1) It has a uniform composition

2) It has only one phase

3) can’t be separated out physically

4) ‘homo’ means the same

Example: a mixture of alcohol and water

Heterogeneous mixture:

1)It has a non-uniform composition

2)There are two or more phases

3)It can be separated out physically

4)‘hetero’ means different

Example: a mixture of sodium chloride and sand
