Homework Help: Chemistry 130

Posted by Taylor on Tuesday, October 13, 2009 at 10:53am.

Can someone please help me with this question? I don't even know were to begin!

1. What is the relationship (i.e. direct or inverse) between pH and hydrogen ion concentration? Remembering that pH= -log[H+].

Thanks for the help!

[H+}=10^-5 pH=5
[H+]=10^-2 pH=2
Thus:
The greater the hydrogen concentration the lower the pH. So is this direct or inverse relationship?

pH = -log[H+]
The above relationship can also be expressed as:
[H+] = 10^(-pH)
or
[H+] = 1 / 10^(pH)
That shows the hydrogen ion concentration is inversely proportional to the pH.
