WebSep 30, 2024 · The pH scale shows how acidic or basic a chemical is in aqueous solution (mixed with water). The scale funs from 0 (most acidic) to 14 (most alkaline or basic), where 7 is neutral pH. Chemicals with pH values from 0 up to 7 are acids, those with a pH value of 7 are neutral, and those with pH values greater than 7 up to 14 are bases. WebIn Figure 3, the pH value corresponds to the number of decimal places under the column for "hydrogen ion concentration." The pH of the solution equals the exponential form of the [H +], with the minus sign changed to a plus. It is much easier to write or say "10 pH" than it is to communicate "a hydrogen‐ion concentration of 0.0000000001 mol/L."
