It may be dissolved in water to regenerate perchloric acid or in aqueous alkalis to regenerate perchlorates. 14. Maybe by microwaving a dry ice bath full of organic material and some oxidant like perchloric acid ? 15. "' Dichlorine heptoxide "'is the chemical compound with the anhydride of perchloric acid . 16. A solution of vanadium ( V ) perchlorate can be made by dissolving vanadium pentoxide in perchloric acid . 17. Perchlorate is the anion resulting from the dissociation of perchloric acid and its salts upon their dissolution in water. 18. It is produced by the careful distillation of perchloric acid in the presence of the dehydrating agent phosphorus pentoxide: 19. One synthesis uses fluorine and perchloric acid , though the action of ClF 5 on water is another method. 20. Fluorine perchlorate is not analogous to perchloric acid because the fluorine atom does not exist as a positive ion.
