If you go one step further than the simple math formula - pH isn't just describing the concentration of hydrogen ions in a solution but rather that solution's ability to donate/accept H+ ions. So a solution of strong acid which is inhibited to fully dissociate into H+ and it's anion would have a pH much lower than the measured value in the solution. As H+ ions are donated, the acid in solution further dissociates providing more H+ ions, so clearly the solution is more acidic than originally measured. This is how mine water and volcanic hot springs end up with negative pH; https://core.ac.uk/download/pdf/17247528.pdf |
