This is a video discussing the theory and practical applications of electrolysis of aqueous solutions. The speaker explains what electrolysis is and how it involves the splitting of compounds using electricity. They then dive into the...

One of the world’s favorite holiday traditions has a long history. Fireworks started in ancient China where people used explosives because they were believed to ward away evil spirits. From their beginnings as simple noise makers to the...

Let's take a look back at the elements sodium, oxygen, argon, arsenic, and zinc.

The video provides an overview of acids, bases, and salts. It explains what acids and bases are, their reactions with metals and each other, and how some of these reactions can be described as neutralization. The video also discusses...

The video discusses instrumental methods in chemistry, specifically flame emission spectroscopy, as a superior alternative to traditional methods such as flame tests and sodium hydroxide tests. It explains how the technique works, where...

In this video I shoot the worlds first liquid metal bullets made from sodium and potassium.



I melted the soft lead from .45 caliber hollow point bullets and replaced it with super soft sodium and potassium metal. When you...

This video covers alcohols. The presenter explains the general structure and chemical properties of alcohols, including their homogeneous series and naming conventions. The two main methods for producing ethanol, a common alcohol, are...

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

Action Potential Physiology (Part 1)

When we learned about periodic trends, we learned about ionization energy. Just how much energy is required to remove an electron from an atom? What about a second electron, or a third? Let's compare a few different ionizations and see...

Who couldn't use a little practice balancing equations? If you've seen my tutorial outlining how to do this, then you're ready for four rapid fire examples to make sure you're ready to do this on your own. Give them a shot!

This video is a tutorial on balancing chemical equations. The presenter discusses the law of conservation of mass and the importance of balancing equations to determine the ratios of reactants and products. They explain the meaning of...

Prof Hal Sosabowski demonstrates a solid spontaneously coming out of solution in this visually beautiful experiment. Just a few crystals are enough to form a nucleation site for a super-saturated solution of sodium acetate. This...

It discusses the trends of chemical properties such as oxidation states, chemical reactivity.

What research is being conducted currently? How does it work? If successful, how can it help society? What careers deal with science and water?<br/>
Properties Of Water, Part 5

Learn the basics about Group 1, as an example of Groups in the periodic table.

We've got two vicinal dihalides with different stereochemistry, and we want to make them. How can we do this? Think about the reactions you know and give it a try!

In this video, I look at Saltatory conduction and explore how it is responsible for moving the action potential quickly along the axon and down to the axon terminals. See how the Myelin Sheaths influence the speed of propagation.

We've learned about ionic and covalent bonds, so we understand the interactions that will occur between a metal and a nonmetal, or between two nonmetals. But what about two metals? Metallic bonding! This ends up being sort of like ionic...

UCSD materials scientist aims to clear hurdles to development of sodium-based rechargeable batteries



Running out of "juice," finding a place to charge up, borrowing a charger, waiting for the charge--it's a...
