What Are Elements?

1. What Are Elements?

Look around you. What do you see? Elements are everywhere. They are the building blocks of all matter on Earth. In this lesson, we will discuss what an element is, how elements are written as symbols, and how elements are the building blocks of all matter.

Using Colligative Properties to Determine Molar Mass

2. Using Colligative Properties to Determine Molar Mass

In this lesson, we will explore the effect of colligative properties on a solution. We will learn how to calculate freezing point depression and see how it can be used to calculate the molar mass of an unknown substance.

Calculating Dilution of Solutions

3. Calculating Dilution of Solutions

Learn what a solution is and how to properly dilute a new solution from a stock solution. Learn the dilution equation that combines molarity, the volume of stock solution and desired solution to determine how much stock solution is needed for the new solution.

Colligative Properties and Raoult's Law

4. Colligative Properties and Raoult's Law

Learn how vapor pressure and osmotic pressure are colligative properties. Learn Raoult's Law and how to use it to determine the vapor pressure of a solution. Learn the equation for determining osmotic pressure and how to use it to determine the molar mass of a substance.

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.

The Rate of Dissolution: Factors and Definition

6. 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

7. 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.

Solutions, Electrolytes and Nonelectrolytes

8. Solutions, Electrolytes and Nonelectrolytes

Learn what a solution is and how it is formed. Learn how to express the concentration of a solution in terms of molarity, molality and mass percent. Discover the differences between an electrolyte and a nonelectrolyte.

How Compounds and Molecules Are Built From Elements

9. How Compounds and Molecules Are Built From Elements

Did you know that elements are like people and have different personalities? A few elements are very shy and love to be left alone. Others are very social and prefer to hang out with friends. In this lesson we will discuss how elements build molecules and compounds.
