Acids, Bases and the Power of Hydrogen

The 1970’s was the decade that illuminated the threat of acid rain to the citizens of the US. It had been known to exist several years before, but the sources of the problem did their best to suppress the information. It wasn’t until the environmental damage became significant enough to draw national attention that it would lead to the US enacting regulations to stop acid rain.

Truthfully, most of the public was probably still unaware of what acid rain actually was. The default mental image that comes to the mind of the non-chemist is large drops of battery acid raining …read more

Looking at the ingredient list of some popular processed foods will produce a puzzled look on the typical hacker’s face. Tricalcium phosphate, thiamine mononitrate, zinc proteinate, pyridoxine hydrocloride… just who the hell comes up with these names anyway? It turns out that there is a method to the madness of chemical name structures. Some of them are well known, such as sodium chloride (NaCl) and hydrogen peroxide (H2O2). Others… not so much. In the early years of chemistry, chemical substances were named after their appearance, affects and uses. Baking soda, laughing gas and formic acid (formic is Latin for …read more

Chemical Formulas 101

It seems like every other day we hear about some hacker, tinkerer, maker, coder or one of the many other Do-It-Yourself engineer types getting their hands into a complex field once reserved to only a select few. Costs have come down, enabling common everyday folks to equip themselves with 3D printers, laser cutters, CNC mills and a host of other once very expensive pieces of equipment. Getting PCB boards made is literally dirt cheap, and there are more inexpensive Linux single board computers than we can keep track of these days. Combining the lowering hardware costs with the ever increasing …read more
