The equation for pOH is the same as that for pH except using the concentration of hydroxide instead of H +: pOH = −log [OH –] Water and its pH. Pure water has a pH of 7 on the pH scale, meaning that it is neutral. Webb30 sep. 2024 · 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. Here is a table of pH values of common chemicals. pH Values of Common Chemicals dickies accessory
