WebApr 14, 2024 · The pH scale is a precise way of classifying the acidity, basicity or neutrality of a solution. As a logarithmic scale, 1 pH unit is ten times stronger, or ten times weaker, than the one below or above it, depending on its position: a pH of 4 is ten times more acidic than a pH of 5, but ten times weaker than a pH of 3. Webrepresents a tenfold change in the acidity or alkalinity of a substance. The range goes from 0 to 14, and around 7 is considered neutral. For example, water with a pH of 5 is ten times more acidic than water with a pH of 6. Additionally, pH of less than 7 indicates acidity, whereas a pH of greater than 7 indicates alkalinity or a base.
