WebThe pH scale ranges from 0 to 14, with a pH of 7 indicating neutrality, values less than 7 indicating acidity, and values greater than 7 indicating basicity. ... The unified absolute pH scale is based on the absolute chemical potential of the proton, as defined by the Lewis acid–base theory. This scale is applicable to liquids, gases, ... WebThe pH scale is a number scale that indicates how acidic or basic a solution is. Acids have a pH below 7 and bases have a pH above 7. Neutral solutions have a pH of 7. On the pH scale, one unit of change represents a 10-fold change in the degree of acidity or basicity. For example, a two unit drop in pH is a 102 or 100 times increase in acidity. northern rebellion plan
