Give an example of a 2 phase mixture and describe how you would separate the substances

First, we should define what a mixture and a two-phase mixture mean.
A mixture is a combination of two or more substances without any chemical reaction occurring between them. Components of a mixture can be separated using physical methods such as heating, filtering, evaporation, .... etc
A two-phase mixture is a type of mixture that contains two different phases of matter, for example solid and liquid phases in one mixture or liquid and gas phases in one mixture.

Now, we can give examples of two-phase mixtures and mention how to separate them:
A mixture of sand and water is considered a two-phase mixture (sand is sold and water is a liquid).
The components can easily be separated using filtration where the sand will remain on the filter paper and water will pass.

Another example is a mixture of sugar and water (sugar is a solid and water is a liquid).
The components can be separated by heating. We can eat the mixture until water evaporates and the sugar is precipitated. The evaporated water can then be condensed into a different container.

Hope this helps :)

Further explanation:

Mixture:

The material that is made up of two or more substances is called a mixture. It has no fixed formula and its composition is also varied. All the individual constituents retain their properties after the formation of the mixture.

Types of mixtures:

1. Homogeneous mixtures

Homogeneous is a Latin word that means the same. These mixtures have a uniform composition throughout. These types of mixtures consist of a single phase only. Air, orange juice and blood are the examples of a homogenous mixture.

2. Heterogeneous mixtures

Heterogeneous is a Latin word that means different. These mixtures that have non-uniform composition throughout. These mixtures have more than one phase. Concrete, soda and chocolate chip cookies are the examples of a heterogeneous mixture.

Characteristics of mixtures:

1. It has a variable composition and has no formula.

2. Mixtures are not formed by any chemical reactions.

3. Mixtures can be either homogeneous or heterogeneous.

4. The constituents of the mixtures can be separated by physical methods such as filtration, heating, drying, distillation, crystallization.

5. The properties of the individual particles of the mixture are retained even after the formation of mixtures.

A mixture of sand and water is an example of a two-phase mixture. Here sand is a solid whereas water is a liquid. The components of the mixture are separated by filtration. Sand will remain on the surface of filter paper while water passes through it.
