Article name

Is there anyway to get the initial p to be minuscule rather than capitalized (or should we just rename the article to Potential of hydrogen)? Wikipedia seems to use a {{lowercase}} template that we don't have. Benjamin Seghers 14:09, 9 October 2007 (CDT)

I've created a {{lowercase}} by simply copying the code from Wikipedia's same template. Not sure if it's allowed, but it worked. Benjamin Seghers 14:27, 9 October 2007 (CDT)

the formula

The pH formula is wrong in reality, pH should be related to the activity (effective concentration) of hydrogen ions, but not just the concentration of hydrogen ions. However, I do not know how to modify the formula, can anyone correct this?

You are right, the pH formula is too simple-minded. It has the form that I (and probably many others) learned in high-school. As high-schools probably still teach it in this form, the formula has some (educational) use. --Paul Wormer 11:59, 3 June 2009 (UTC)
