100 Chemical Myths bargains with well known but mostly unfaithful misconceptions and misunderstandings regarding chemistry. It comprises lucid and concise factors reduce via fallacies and concrete legends which are universally suitable to a world viewers. quite a lot of chemical myths are explored in those parts; meals, medicinal drugs, catastrophes, chemical compounds, and environmental difficulties. Connections to pop culture, literature, videos, and cultural heritage carry the reader’s curiosity while key thoughts are fantastically annotated with illustrations to facilitate the certainty of surprising fabric. Chemical Myths Demystified is pitched to participants with no formal chemistry heritage to fledgling undergraduate chemists to professional researchers and beyond.

Crucial activity of the analytical chemist, other than the purchase of experimental information, is the coordination and interpretation of such facts when it comes to the qualitative and quantitative composition of the try substance. As within the outdated story of the blind males and the elephant, a unmarried statement or try out, no longer thought of at the side of others, could lead on to completely faulty conclusions.

Example text

Needless to say, this did not occur without much scientific debate, some of which were quite passionate: until 1988, American freon-producer DuPont Co. paid a few scientists to follow Sherwood Rowland everywhere he travelled and debate his scientific views, mostly based on reasoning motivated by financial interests. The Montreal Protocol has been ratified by 196 countries and most freon-like substances have already been phased out. Some positive effect is already detectable: the ozone hole above the Antarctic was largest in 2006, and most recent measurements indicate that the loss of ozone in the troposphere has stopped—the trend might even have reversed somewhat.

The constituent elements would have not been decontaminated on site, they would have been transported to a hazardous waste deposit in Galgamácsa, a village about 200 km away and close to the Hungarian capital Budapest. At the Vekerd site, batteries would have been disassembled to re-capture lead, sulfuric acid and two different kinds of plastic. In a 2003 referendum, the inhabitants of the village gave their support to build the facility. The mayor of neighboring Zsáka, however, intervened. He argued that lead re-processing must not be allowed in an area protected by a program called Nature 2000, in which many farmers have already switched to organic farming.

26 1 Misconceptions in General It may be surprising to learn that Mendeleev’s success rate in his predictions was only 50 %. It is quite interesting to note that while the successful predictions contributed significantly to the general acceptance of the periodic table, the failures did not have the opposite effect. These unsuccessful predictions did not lack logic, but chemistry turned out to confirm different lines of thought later. One should remember that Mendeleev did not have any idea about the concept of atomic number, neither did he have any information about the electron structure of atoms.
