This is false. pH=-log[H₃O] therefore pH is a logarithmic scale and the if you double the concentration the pH won't go down by 2. When you double the concentration of H₃O, the pH doesn't actual change a whole lot. If you play around with the different concentrations and then doubling them, you will only find that the pH drops by about. 301 each time.
