In 46 episodes, Hank Green will teach you chemistry! This course is mostly based on the 2012 AP Chemistry curriculum.

Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles - the proton, neutron, and electron - come together in trillions of combinations to form ... everything.

The Nucleus: Crash Course Chemistry #1

A unit is a frequently arbitrary designation we have given to something to convey a definite magnitude of a physical quantity and every quantity can be expressed in terms of the seven base units that are contained in the international system of units.

Stoichiometry - Chemistry for Massive Creatures: Crash Course Chemistry #6

Dihydrogen monoxide (better known as water) is the key to nearly everything. It falls from the sky, makes up 60% of our bodies, and just about every chemical process related to life takes place with it or in it. Without it, none of the chemical reactions that keep us alive would happen.

Water & Solutions - for Dirty Laundry: Crash Course Chemistry #7

Last week, Hank talked about how stuff mixes together in solutions. Today, and for the next few weeks, he will talk about the actual reactions happening in those solutions - atoms reorganizing themselves to create whole new substances in the processes that make our world the one we know and love.

Hank talks about the actual reactions happening within solutions - atoms reorganizing themselves to create whole new substances in the processes that make our world.

Acid-Base Reactions in Solution: Crash Course Chemistry #8

A lot of ionic compounds dissolve in water, dissociating into individual ions. But when two ions find each other that form an insoluble compound, they suddenly fall out of solution in what's called a precipitation reaction.

Precipitation Reactions: Crash Course Chemistry #9

All the magic that we know is in the transfer of electrons. Reduction (gaining electrons) and oxidation (the loss of electrons) combine to form Redox chemistry, which contains the majority of chemical reactions.

Gases are everywhere, and this is good news and bad news for chemists. The good news: when they are behaving themselves, it's extremely easy to describe their behavior theoretically, experimentally, and mathematically. The bad news is they almost never behave themselves.
