"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. " - Ph to alkalinity conversion
