Bio/chem relation between pH and [H+]

  1. Oct 17, 2006 #1
    Hi my question is How does the pH relate to the concentration of Hydrogen ions?

    what I think is The relationship between the pH and the concentration of Hydrogen ions is that the -log of the hydrogen ion concentration is equal to the pH, but this doesn't seem right at all.

    can someone please help me out?:confused:

    The pH is [tex] pH = -\log[H^{+}] [/tex]. So you are correct.

    I thought there would be a more complicated answer

    Nope. See pH definition and pH scale for more details - but they won't change what courtrigrad have already wrote.
