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. 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. grand panama beach resort condos for rent
