I think the external link to the page on making flash powder should be removed. Not only is flash powder illegal, the guide is dangerously inaccurate and vague. No one should be making 100g of flash powder, its enough to take off your hand! —Preceding unsigned comment added by Zilali (talk • contribs) 20:28, 21 July 2008 (UTC)[reply]

The picture of the structure of KClO4

Since when did potassium form covalent compounds? The whole ClO4- has a charge of 1- over the whole of it, and K+ sits next to it.

I agree, the picture should be a salt, as for Potassium Chlorate. —The preceding unsigned comment was added by 67.150.214.208 (talk) 05:47, 10 March 2007 (UTC).[reply]

Melting and boiling points

Is melting point really higher than boiling point???? 84.49.197.41 14:30, 27 May 2007 (UTC)[reply]

Ok... um... I don't know, but how is the melting point 610 when the boiling point is only 400? It doesn't really make sense... —Preceding unsigned comment added by 71.37.187.192 (talk) 06:21, 10 March 2008 (UTC)[reply]

Doesn't it decompose before it melts? If so the decomposition temperature should be written somewhere and "(decomposes)" written after melting point in the info box, as it is for other compounds. --91.125.204.12 (talk) 02:17, 26 April 2010 (UTC)[reply]

There's something strange going on. The MSDS linked has the melting point above the boiling point. I found another source that lists a melting point at 525C for some reason. But most pages, including http://www.sigmaaldrich.com/catalog/product/sial/60441?lang=en and http://www.sciencelab.com/msds.php?msdsId=9924687 seem to agree that there's no boiling point at all, and KClO4 decomposes at 400C. Bit afraid to edit it myself, because I'm not certain, but I'd think that that last option is the most likely. --145.97.223.35 (talk) 07:11, 1 August 2013 (UTC)[reply]

Solubility

There are two different water solubilities mentioned in the article, one in the text and one in the infobox. Neither is referenced. --Ed (Edgar181) 13:00, 10 December 2007 (UTC)[reply]

In the scifi television series "The Expanse", season 1, episode 1, at 22:12, the new XO starts a night shift in the pilot's seat of an asteroid mining spacecraft by scraping off the red material at the tip of a wooden match and adding it to his coffee. Could this be Potassium Perchlorate 1) to reduce uptake of radioactive elements in their drinking water 2) sugar to sweeten/flavor the coffee (which the character remarked was horrible immediately previously) 3) as a stimulant? 4) haleucenagenic? (he reviews a distress signal and hears voices in the background)
