What is a Solution in Science? - Definition & Examples

1. What is a Solution in Science? - Definition & Examples

The air we breathe, what we drink, as well as products in our household - these are a few examples of solutions we encounter every day. In this lesson, we will discuss what a solution is, the different types, as well as examples.

Concentration of Solutions: Definition & Levels

2. Concentration of Solutions: Definition & Levels

In this lesson, we learn about solutions and what makes up a solution. We also look at solution concentration levels and how to calculate the concentration of a solution.

The Rate of Dissolution: Factors and Definition

3. The Rate of Dissolution: Factors and Definition

Learn what dissolution is and the factors that affect the rate of dissolution, such as temperature, surface area, polarity and pressure. Learn what miscible and immiscible mean in regards to liquids.

Solubility and Solubility Curves

4. Solubility and Solubility Curves

Learn what solubility is as well as the definitions of 'saturated,' 'unsaturated' and 'supersaturated.' Learn how to determine the solubility of a substance in water by using a solubility curve. Discover the effects of pressure and temperature on the solubility of liquids, solids and gases.

Calculating Molarity and Molality Concentration

5. Calculating Molarity and Molality Concentration

Learn the abbreviations and meaning of molarity and molality. Then apply what you have learned by going over some sample calculations with given concentrations.
