Webb26 juni 2024 · The pH concept was developed to make it easier to report “hydrogen ion” concentration in solution. For example, it is tedious to keep saying that the concentration of hydrogen ion– [H+] — in water at 25 °C is 0.0000001 moles per liter. If this same value is written in standard notation, we will get 10 -7 moles per liter.
