Title: PH
Post by: wmccall on October 22, 2007, 01:57:22 pm

I've been dealing with PH and taking care of my water for almost 5 years, but I realized today I didn't know what PH stood for.  I'll bet I'm not alone.  Anyone?     Clue, its not Perfectly Happy, or Probably Horny.

The most I know is that the p is a little p and the H is a big H.  
That must be important, but I don't know why.

Damn my liberal arts degree!!!!

Bill

   There is a funky Latin term for it but in English its hydrogen potential or pH


Now my wife can't say I'm full of useless information because someone just asked and it was useful ;D

The symbol for hydrogen is "H".

 A lower case p in front of some symbol is an indication to take the negative log of that quantity.
 
So pH is the negative log of the hydrogen ion concentration in the water solution.  This makes the numbers easier to work with.   A hydrogen ion concentration of 1.0 x 10^-7  will give a pH = 7, a much easier number to deal with.

I have got to find a way to use that phrase in standard conversation before I die.   :)

I don't know about the "negative" but  "log"  might be worked in somewhere, somehow   ;)
