Curriculum subtopic:   Mixtures, including Dissolving

Difficulty level:  

Worksheet Overview

A solution is a transparent (see-through) liquid. Solutions can never be cloudy or opaque. For example, the liquid below is orange but it is clear, so it is a solution.

Solution in flask

 

On the contrary, this liquid is not a solution:

Bottle of milk

In a solution, a solid dissolves in a liquid.

The solid particles are held tightly together in a fixed arrangement, but that arrangement is broken up by the liquid particles.

The solid substances that dissolve are called solutes and the liquids they are dissolved in are called solvents. A solute dissolved in a liquid makes a solution.

Substances that dissolve are said to be soluble, whereas those that do not dissolve are said to be insoluble.
