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.

Answer:

False

Explanation:

We can use an example to ilustrate the problem. For example we can use a concentration values of [tex]4x10^-^3[/tex] and [tex]6x10^-^3[/tex] (a difference of 2). Using the pH formula we can calculate the pH value for each concentration.

[tex]pH=-Log[4x10^-^3]=~2.39[/tex]

[tex]pH=-Log[6x10^-^3]=~2.22[/tex]

The difference between these values is 0.18 . Due to the logarithm, the difference in the concentration is not the same in the pH values.
