After writing an answer on worldbuilding.SE, I came here to ask a question. How long would it take to dissolve a human body using fluoroantimonic acid?

I understand that since the human body isn't homogenous, it's a bit tough to get the exact calculation, but lets say we create a mannequin using the material in the human body that fluoroantimonic acid takes the longest time to dissolve - how long would it take?

    $\begingroup$ As for the question, my gut answer is no. Acids are not magic dissolving fluids. You'll certainly hydrolyze the living daylights out of esters and related bonds, of course. $\endgroup$ Aug 5, 2015 at 18:59
  • $\begingroup$ @etherealflux we already know it takes 2 days (roughly) to dissolve a body in a vat of sulfuric acid. That tells me that it's at least possible to do the task at hand with an acid that basically dissolves anything not teflon. $\endgroup$

    $\begingroup$ @etherealflux Funnily enough, an acid weaker than fluoroantimonic acid was named "magic acid", because of its surprising ability to protonate even alkanes, meaning it could dissolve a candle. $\endgroup$ Aug 5, 2015 at 19:02
  • $\begingroup$ Welp, that'll do the trick. I remember reading about that once - stabilizing carbocations is insane. $\endgroup$ Aug 5, 2015 at 19:02
