> [@](#): > > pH is a measure of the acidity or alkalinity of a solution. Solutions with a pH less than seven are considered acidic, while those with a pH greater than seven are considered basic (alkaline). pH 7 is considered neutral because it is the accepted pH of pure water at 25 °C, although, strictly, pure water cannot be assigned a pH value. Source: [pH - Wikipedia](http://en.wikipedia.org/wiki/PH) Using the above ph rating, what’s your pH rating of PH? Mine is close to zero. I have no sympathy for Paris Hilton. I hope she spend her entire sentence in jail. ---

pH is minus the log of the hydrogen ion concentration. It runs from 1 to 14, with low numbers as acidic and high ones basic, with 7 as neutral. Thus, you can’t have a pH of ner zero, unless you accept something at 1 or slightly higher. This nerdy geeky answer brought to you by CalMeacham, who has a Ph of “D” ---

I’m 7.43. On the one hand, I can’t work up any anger against her or against rich people in general–I’m glad that there are stupidly rich people in the world and hope to one day be one of them. On the other hand, she does seem pretty vapid, spoiled, and self-absorbed, so I’m not rooting for her at all. That brings me to a neutral 7… from which my sympathy tips slightly in her favor because the stupid judge is obviously raking her through the coals for publicity purposes. From what I can tell, she is _not_ being treated like an average person–she’s being treated worse. ---

You can even get [Negative pH acids](http://en.wikipedia.org/wiki/Negative_pH).
