Ph scale logarithms

  1. Aug 20, 2014 #1
    How do I work out how many times more acidic a ph value of 6.8 is compared to 8.6? For example.

    Ps I'm not au fait with the formula shortcuts and they don't display on my iPhone so if this can be avoided It would be much appreciated.

    Thanks

    Concentration of H+ is about 63 times higher at pH 6.8 than it is at pH 8.6, that's correct. Whether the solution is 63 times more acidic depends on how you define "acidity".
