Sagot :

Explanation:

1. In chemistry: a pure substance consists only of one element or one compound. a mixture consists of two or more different substances, not chemically joined together.

2. Mixtures can be classified into three types: suspension mixture, colloidal mixture or solution.

3. In most technical applications homogeneous means that the properties of a system are the uniform throughout the entire system; heterogeneous (also inhomogeneous) means that the properties change within the system. ... For example, homogeneous systems have the same composition, density and pressure throughout.

4. Characteristics of Solutions

It is a homogeneous mixture.The size of solute particles in the solutions is extremely small. ...The particles of a solution cannot be seen even with a microscope.The particles of a solution pass through the filter paper. ...It is very stable.

5. Components of solutions

A solvent constitutes the larger component of the solution. For example, a solution of sugar in water is solid in the liquid. Here, sugar is the solute and water is the solvent. Solute: The component of the solution which dissolves in the solvent is called solute.
