Practice Problem: Analyzing Acid-Base Equilibria
Acids! Bases! Conjugate acids! Conjugate bases! We definitely have to be able to label such things, and we should also know how to state which direction in an acid-base equilibrium is preferred. To do this we should know how to tell...

What Are Structural Isomers
In this video we will look at some different structures of butane - so they all have 4 carbons but just arranged differently.
We will also look at the the 5 different isomers for hexane - they all have 6 carbons (and hence are hexane...

Acid-Base Equilibria and Buffer Solutions
Remember those pesky iceboxes? Weak acids and bases establish equilibria, so we have to do iceboxes to figure out things about them. But don't worry, buffers are neat.
