Hearing the word "superacid" may evoke memories of that scene from Breaking Bad, but perhaps counterintuitively, the strongest acid on Earth wouldn't be able to destroy your bathroom.

One of the most famous elements in the periodic table doesn't really belong anywhere chemists would like to put it.

For thousands of years, water was thought to be an element. That is, until some of the greatest chemists in the world managed to crack it open.

Fake pharmaceuticals are a multi-billion dollar problem around the world.

Made and packaged to look like the real deal, these phonies may conta

fraction of the active ingredients or none at all. these fake
drugs can...

Humans love to make perfumes and fragrances from the weirdest sources, And to protect those sources, we sometimes come up with synthetic alternatives....which then create their own sets of environmental problems.

Time Magazine has called it "the most horrible drug in the world," and last month, it hit the US. Because seriously, why would you take a drug that rots your flesh, bones, and brain?!

Hank and PhD candidate Casey Massena go deep into the chemistry of a molecule that Casey helped create! Then Jessi joins the show to show off Ecuador, one of her many conures!

Inside chemistry labs, chemists work with what they call superacids. No one's found a specific use for such a fantastically strong acid yet, but chemists are actively looking for one.

In the mid-ninth century, Chinese chemists, hard at work on an immortality potion, instead invented gunpowder. They soon found that this highly inflammable powder was far from an elixir of life -- they put it to use in bombs against...

What's the science behind a sublime perfume? With charm and precision, biophysicist Luca Turin explains the molecular makeup -- and the art -- of a scent.

In this video Paul Andersen explains how an overall chemical reaction is made up of several elementary steps. The stoichiometry of this equation can be predicted but the rate law must be measured. If the elementary steps of the...

Sodium pentothal, the so-called "truth serum,' is real! But does it work? Find out what "truth serums' do, and how your brain lets you tell lies.

You're just in time to help Jessi and Squeaks with their baking soda and vinegar experiment! Then, stick around to learn all about chemists, special scientists who study chemicals!

We have many alternatives to sugar, but where are all the salt substitutes?

The world’s first artificial pigment, Egyptian blue, may help scientists prevent forgery and even save lives.

Models are great, except they're also usually inaccurate. In this episode of Crash Course Chemistry, Hank discusses why we need models in the world and how we can learn from them... even when they're almost completely wrong....

Chemists need stoichiometry to make the scale of chemistry more understandable - Hank is here to explain why, and to teach us how to use it.

Ketones and aldehydes are all around and inside us, from the strong smelling component of nail polish remover, acetone, to hormones in our bodies, to drug treatments for allergies, COVID-19, and even cancer! We’ve already learned a bit...

You might not believe it, but the same chemistry that brought us bulletproof vests and modern sailing sails also gave us the technology to build your smart phone. But that doesn’t mean these chemists were thinking about these...

From Mendeleev’s original design to physicist-favorite “left-step” rendition, the periodic table of elements has gone through many iterations since it was first used to organize elements 150 years ago - each with its own useful insights...

In 1869, Russian scientist Dmitri Mendeleev created the Periodic Table, ordering the naturally occurring elements by their structure and properties. His Periodic Table changed the course of Chemistry forever, and even predicted the...

The 17th century German chemist Johann Becher proposed that an element, phlogiston, was released when substances burned. He was wrong, and his incorrect theory led many early chemists to misunderstand the significance of some of their...

Learn about Marie Curie, the extraordinary woman scientist who won multiple Nobel Peace Prizes and helped develop early x-ray technology.

After learning about the different kinds of organometallic reactions, we are ready to learn about transition metal catalysis. This is an incredible field that has pushed organic synthesis forward in leaps and bounds over the past 50...
