Solutions with a pH below 7.0 are acidic while solutions with a pH above 7.0 are basic (or alkaline). Since the pH scale is logarithmic, not linear, a solution of pH 1 would have ten times (not twice) the [H+] that a solution of pH 2. Likewise, a solution of pH 12 would be 10 times more alkaline than a solution of pH 11. pH ...
