1. Examples of superacids are fluoroantimonic acid, magic acid and perchloric acid . 2. The analogous graphite perchlorate can be made similarly by reaction with perchloric acid . 3. I notice that HCl is a weaker acid than say, perchloric acid . 4. Michelle flees, coming across Emmett's body dissolving in perchloric acid . 5. It slowly hydrolyzes back to perchloric acid , which is also hazardous when anhydrous. 6. Correspondingly, perchloric acid is quite stable. 7. The laboratory synthesis entails the acidification of aqueous solutions of sodium molybdate with perchloric acid : 8. It is structurally similar to perchloric acid , but lacks the hazards associated with oxidants. 9. The sulfonic acid derivative, trifluoromethanesulfonic acid, is comparable in strength to perchloric acid . 10. The same explanation can explain why perchloric acid is a much stronger acid than chlorous acid.
