WebbThe pH scale is a logarithmic scale corresponding to the hydronium ion concentrations of aqueous solutions. The pH is equal to the negative logarithm (base 10) of the hydronium ion concentration. pH = -log [H3O+] This *can be restated in an equation for calculating the hydronium ion concentration from the pH. [H3O+] = 10-pH. Webb30 sep. 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.
