"However, it is strange that perchlorates are even weaker oxidizing agents than chlorates."
How is this strange? AIUI, the perchlorate (ClO4) has a net noble gas electron configuration, making it relatively stable; the chlorate (ClO3), has a less stable electron configuration, and is therefore more reactive, despite having fewer oxygen atoms. I plan to remove / change this sentence in the near future if there are no objections. Evand 04:44, 25 Apr 2005 (UTC)
This page lists the pKa of Perchloric acid as -7.00 ... however, the acid dissociation constant page lists it as -10.00. Additionally, the acid dissociation page and main page for Hydrochloric acid list that compound's pKa as -8.00, suggesting that Perchloric acid's pKa on this page might be inaccurate. --gabe 21:07, 22 September 2006 (UTC)
- According to CRC Handbook of Chemistry and Physics, 87th edition the pKa of Perchloric acid is -1.6 (8-14). The same numeric value is given by Lange's Handbook of Chemistry, 15th edition. An older (1985) German Textbook (Hollemann-Wiberg, Lehrbuch der Anorganischen Chemie) states pKa=-10. I will try to get more info on that.--Xenofonos 20:14, 26 October 2007 (UTC)
the statement "organic material such as cloth or wood" is functionally, nearly useless. i believe but am not certain that sugar polymers, i.e. cellulose are the primary concern, what is the interaction of poly-aromatic hydrocarbons, i.e. naphthalene. what is the interaction of acetylene, experience says that this is not particularly hazardous.
