Equilibrium: Chemical and Dynamic

1. Equilibrium: Chemical and Dynamic

Learn the definition of chemical equilibrium and how it is dynamic. Discover what the equilibrium constant is and how it shows whether the reaction favors the reactants or products. Learn how chemists designate equilibrium in an equation and how they show the difference in reaction rate.

LeChatelier's Principle: Disruption and Re-Establishment of Equilibrium

2. LeChatelier's Principle: Disruption and Re-Establishment of Equilibrium

Learn how Le Chatelier's Principle describes the disruption and re-establishment of equilibrium. Learn to explain the factors that disrupt equilibrium, such as concentration, temperature, and pressure. Learn how each of these factors affects a system in equilibrium.

Using a RICE Table in Equilibrium Calculations

3. Using a RICE Table in Equilibrium Calculations

Learn what the RICE table is and how to fill in the table with the reaction, initial concentration, change in concentration and amount of product and reactants at equilibrium. Learn how to use the RICE table to calculate the concentrations and amounts and the equilibrium constant of equations at equilibrium.

Solubility Equilibrium: Using a Solubility Constant (Ksp) in Calculations

4. Solubility Equilibrium: Using a Solubility Constant (Ksp) in Calculations

Learn the definition of solubility and solubility constant (Ksp) in this lesson. Interpret solubility constants and make calculations involving the dissociation of a slightly soluble compound given molar solubility.

The Common Ion Effect and Selective Precipitation

5. The Common Ion Effect and Selective Precipitation

Learn what the common ion effect is, how to make equilibrium calculations involving it, and how to find the concentrations of ions when adding reactions in equilibrium to solutions that already contain ions.

Acid-Base Equilibrium: Calculating the Ka or Kb of a Solution

6. Acid-Base Equilibrium: Calculating the Ka or Kb of a Solution

In this lesson, you will review acid and base strength and acid and base dissociation. You will then learn what acid and base dissociation constants (Ka and Kb) are, what they mean, and how to perform calculations involving them.

Acid-Base Buffers: Calculating the pH of a Buffered Solution

7. Acid-Base Buffers: Calculating the pH of a Buffered Solution

Learn what a buffer is, how it works, and why we benefit from having our blood buffered. Learn how to calculate the pH of a buffered solution before an acid or base is added and how the pH changes after an acid or base is added.
