1. Dissociation Constant and Autoionization of Water
Learn the meaning of auto-ionization of water, sometimes called self-ionization, where water acts as a proton donor and acceptor to form both hydronium and hydroxide ions. Learn what the auto-ionization constant is and how to use it to determine the concentration of either hydroxide or hydronium ions in a solution when given the other value.

2. Precipitation Reactions: Predicting Precipitates and Net Ionic Equations
Learn what a precipitate is and predict when it will form in an aqueous chemical reaction, usually a double-replacement reaction. Learn what an ionic equation is, how it differs from a net ionic equation and how to write a net ionic equation.

3. Colligative Properties and Raoult's Law
Learn how vapor pressure and osmotic pressure are colligative properties. Use Raoult's Law 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.

4. 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.

5. Calculating Values for Electrolyte Solutions
In this lesson, we will talk about what defines a solution, an electrolyte solution, and then how to calculate the concentration of those solutions using some common units of concentration.

6. Calculating Boiling-Point Elevation of a Solution
In this lesson, you will learn how to calculate the boiling point of a solution using a simple equation. Additionally, you will review the concepts of solutions, molality, and electrolytes.
