I believe both negative pH and pH greater than 14 are possible in aqueous solution -- consider for example a solution of Sodium Hydroxide with concentration greater than 1 mol/liter (a search for ph and "greater than 14" turns up a bunch of references).
Jan 4th, 2013 at 07:04 GMT
Yeah, I felt the same way, plus there is already a pH question. You could always ask something like "number of lanthanide elements' (or actinide) and then still have the 14 be the answer.

Great, thanks for both your comments. I had been taught that higher concentrations wouldn't fully dissociate in aqueous solutions and were therefore limited by the dissociation constant of water, but no doubt there's more to the story. I'll adopt your suggestion of changing it to lanthanides, and thanks for the editor's pick.

Fun stuff, good quiz. Elimination is the way to go!

Good thing I encountered the angstrom clue before the googol clue, or I would have made a careless mistake.
Jan 6th, 2013 at 02:39 GMT
Oh, me and my carelessness. Number of
in googol, not zeros.

This made me feel very smart...until I ran out of time. :(
