I looked up the etymology of pH, and according to one source
it's the following:
pH, from P, for German Potenz "potency, power"
+ H, symbol for the hydrogen
ion that determines acidity or alkalinity
Okay, so a potent solution of hydrogen would naturally be a solution with many hydrogen cations, right?
But when we look at the pH scale it looks like this. So, given that the etymology is correct
, wouldn't it make more sense if the scale were reversed? So, a potent solution of hydrogen cations would have a high number, say pH 14.
