      I didn’t know this one – but I tried to look it up for you!
      .
      Apparently it was a Danish chemist called ” Søren Peder Lauritz Sørensen” – WHAT A COOL NAME!
      .
      pH actually stands for “potential of Hydrogen” (or in some places I’ve seen “power” instead – it’s from the German word “potenzt”) – and that’s because acids have lots of Hydrogen ions to spare, while Alkalis want more of them, and that’s what the pH scale is based on.
