WebOct 6, 2024 · Use the change-of-base formula for logarithms. In chemistry, the pH scale is used as a measure of the acidity or alkalinity of a substance. Substances with a pH less than are considered acidic, and substances with a pH greater than are said to be alkaline. Our bodies, for instance, must maintain a pH close to in order for enzymes to work properly. WebJul 21, 2024 · The scale ranges from 0 to 14 with the number in the middle (7) representing a point where the number of hydroxide ions and hydronium ions is equal. Substances with a pH of 7 are said to be "neutral." The pH scale is logarithmic, meaning that the difference in acidity or alkalinity from one whole pH value to the next changes by a factor of ten.
