[NurdRage] Make sulfuric acid from oxalic acid with the sun ( www.youtube.com ) Not very practical, but the chemistry is interesting. Producing a strong acid from a weak acid by using precipitation as the driving force is something I don't see very often.
[NurdRage] Measuring Density with Pycnometers, Hydrometers, and Graduated Cylinders ( www.youtube.com ) A bit of analytical chemistry for a change. I had never heard of a pycnometer!
[NurdRage] Make Potassium Nitrate and Sodium Nitrate from Calcium Nitrate - An Alternative to Ammonium Nitrate ( www.youtube.com ) Very useful video. Nitrate salts are a foundational feedstock in amateur (and professional) chemistry....
Thalidomide - Periodic Table of Videos ( www.youtube.com ) A long-time viewer of Periodic Videos grew up to study chemistry, and invented a new synthetic route for thalidomide....
