pH

[ed84c]

I was wondering wether or not what I believe to be the explanation for pH is correct;

 

In pure water there is 2 H atoms with a total mass of 2. Coupled with teh mass of 14 it becomes 14/2 or 7 a neutral pH.

Since it seems were talking about the H way of being acidic, first of all, they are H+; hydrogen ions; protons. There are also other ways of being acidic (such as the Brønsted-Lowry approach, which is pretty much the same only with H3O+). pH in this case is the negative logarithm of the hydrogen ion concentration, and so it is in the B-L approach. For example, in a solution where there's 0.1mol H+ and 0.9mol H2O, the pH is one. A solution with 0.01mol H+ and 0.99 H2O has a pH of 2 and so on. If due to lack of sleep I have screwed up something, please, correct me.
