A pH of 7 is neutral. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more ,acidic, than the next higher value (For example, a pH of 4 is 10 times more ,acidic, than 5, and 100 times more ,acidic, than 6) and each whole pH value above 7 is ten times more basic than the next lower value.
