bio/chem relation between pH and [H+]

[aisha]

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

I thought there would be a more complicated answer

Nope. See pH definition (http://www.chembuddy.com/?left=pH-calculation&right=pH-definition) and pH scale (http://www.chembuddy.com/?left=pH-calculation&right=pH-scale) for more details - but they won't change what courtrigrad have already wrote.
