Titration of Strong Acid With Strong Base

9th - Higher Ed
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)

9th - Higher Ed
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

9th - Higher Ed
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.
