Molarity and Dilution
Now those pesky moles are swimming! But how much solute is there? Let's learn about how we measure concentrations of solutions.
Professor Dave Explains
Molality and Colligative Properties
Solute particles interfere with the physical processes a solution may undergo. These are known as the colligative processes of a solution. Ever wonder why we put salt on icy streets? Find out here!

Le Chatelier's Principle Part 1
What exactly is Le Chatelier's Principle? And why is it important to learn it to understand chemical reactions? Find out in this video!
Professor Dave Explains
Chemical Equilibria and Reaction Quotients
Many chemical reactions don't just go one way, they go forwards and backwards. Once there is balance between the two, this is an equilibrium. And we need to be able to predict how much stuff there will be at equilibrium! Get ready to...
