Webb26 juni 2024 · For example, the pH of 12M HCl (hydrochloric acid) is calculated to be -log (12) = -1.08. But, you can't measure it with an instrument or test. There isn't any special litmus paper that turns a color when the value is below zero. pH meters are better than pH paper, yet you can't just dip a glass pH electrode in the HCl and measure a negative pH. http://marz-kreations.com/Chemistry/Analysis/Quantitative/167f-Conc_HydroChloricAcid.html
