Tools. Exams. Video. Other. Molecules with Silly or Unusual Names. Arsole Yes, believe it or not, there is actually a molecule called Arsole... and it's a ring!
It is the arsenic equivalent of pyrrole, and although it is rarely found in its pure form, it is occasionally seen as a sidegroup in the form of organic arsolyls. For more information, see the paper with probably the best title of any scientific paper I've ever come across: "Studies on the Chemistry of the Arsoles", G. Markl and H.
Hauptmann, J. The O Level Chemistry Tuition Centre. We have all heard of pH scale, but exactly is that and how is it related to Acids, Alkalis and Salts in O LEVEL CHEMISTRY. • Scale range from 1 to 14 (theoretically should be 0 to 14) • Indicates whether a solution is Acidic, Alkaline or Neutral • The LOWER the pH value, the HIGHER the Concentration of Hydrogen ions (H+) in the solution and the STRONGER the acid • The HIGHER the pH value, the HIGHER the Concentration of Hydroxide ions (OH-) in the solution and the STRONGER the alkali Let us now take a look at how pH scale is related to things that we see and hear in our daily life.
