Talk:Potassium tetraperoxochromate(V)

Colour
The crystals are deeply red-brown (visible best under a microscope); glittering and seemingly black, but not brown. Never put an explosive in a glass container! And look here for properties: http://www.sciencemadness.org/smwiki/index.php/Potassium_peroxochromate That's how it looks really! --FK1954 (talk) 18:12, 9 July 2018 (UTC)
 * btw: the crystals are octahedral and explode at 170 °C (according to Jander-Blasius) leaving a yellow residue. --FK1954 (talk) 08:25, 10 July 2018 (UTC)

Well, I saw the crystals under my microscope (beautiful) and watched the acoustic report at overheating. ;) --FK1954 (talk) 08:25, 10 July 2018 (UTC)
