pH is a measure of the acidic or basic (alkaline) nature of a
solution. The pH scale ranges from 0 (most acidic) to 14 (most basic).
- A neutral solution (pure water) has a pH of
7.
- Solutions with a pH less than 7 are acidic, with 0 being the
most acidic.
- Solutions with a pH greater than 7 are basic
(alkaline), with 14 being the most basic.
