Buffers, the Acid Rain Slayer: Crash Course Chemistry
In this episode, Hank talks about how nutty our world is via Buffers! He defines buffers and their compositions, talks about carbonate buffering systems in nature, acid rain, pH of buffers, and titration. Plus, a really cool experiment...

Nomenclature - Crash Course Chemistry
Ever feel like there's a international team of bad guys changing all of the easily remembered chemical names and turning them into test-failing, number-infused, pain in the neck names? Well... you're not wrong. IUPAC exists but try to...

pH and Buffers
In this video Paul Andersen explains how buffer solutions maintain pH in a solution. A buffer solution is made up of a weak acid and its conjugate base. As strong acids or bases are added the pH remains stable. A good buffer solution has...

Acid-Base Equilibrium
In this video Paul Andersen explains how acid-base chemistry can be understood in terms of equilibrium. Water is present in all acid-base chemistry and is amphoteric in nature. The Ka and Kb values can be used to determine the strength...

Acidification of Water
We use a drinking straw, some water and universal indicator to show that breathing out creates acid. Universal indicator is added to the water to show its pH value. When we blow into the water the indicator changes colour showing that...

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.

How Are Strong & Weak Acids Different
Learn the basics about strong and weak acids, and how they differ. Strong acids are often used in School Science labs for experimentation but they have important uses in industry and the everyday world. Sulphuric acid for example is...
