"The pH scale measures how acidic or basic a substance is. It ranges from 0
to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater
than 7 is basic. Each whole pH value below 7 is ten times more acidic than
the next higher value. For example, a pH of 4 is ten times more acidic than a
pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. The same
holds true for pH values above 7, each of which is ten times more alkaline
(another way to say basic) than the next lower whole value. For example, a pH
of 10 is ten times more alkaline than a pH of 9."
From the site you suggested.
Thanks again Jim,
