Common Scientific Glassware and the Undergraduate Chemistry Laboratory
Before we dive into all kinds of fascinating chemistry laboratory techniques, we should familiarize ourselves with all the different equipment we will be using to perform these techniques. The chemistry lab is full of neat-looking...

Titration of Strong Acid With Strong Base
One of the most commonly performed techniques in the general chemistry laboratory is the acid-base titration. This is an analytical technique that we can use to determine the concentration of some analyte by titrating with some titrant...

Performing Thin Layer Chromatography (TLC)
We've learned a few separation techniques, so how about one more? Chromatography separates components of a mixture by virtue of their differing polarities, and thin layer chromatography, or TLC, is an invaluable technique that is used...

Acid-Base Titration
Any introductory chemistry class will include titrations, and to do these, you have to do math. But you get to see pretty colors, too! Here's a quick run through of the stoichiometry of it all.
