Hi, what do you want to do?
Professor Dave Explains
Acids and Bases, pH and pOH
We've all heard the terms acid and base. What do these mean? Don't just tell me about pH, silly. What structural detail makes a molecule an acid or a base? You don't know? Well, you'd better watch this then. You don't want to be...

Practice Problem: Calculations Involving pH and Ka
We know a bit about acids and bases, including the definitions of pH and pKa, as they relate to an acid-base equilibrium. If we have a weak acid and its concentration, as well as the pH of the solution, can we calculate the Ka for the...

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.

Senior Chemistry: Acids and Bases 3
Chemguy explains how to find the hydronium concentration of a solution. The video is not engaging but it is educational. If one of your chemistry charges misses this lecture in class, you can have them watch this at home to make up...
