WebAs we learned earlier, the hydronium ion molarity in pure water (or any neutral solution) is 1.0 × 10 −7 M at 25 °C. The pH and pOH of a neutral solution at this temperature are therefore: pH = −log [H 3 O +] = −log (1.0 × 10 −7) = 7.00. pOH = −log [OH −] = −log (1.0 × 10 −7) = 7.00. And so, at this temperature, acidic ... WebJan 30, 2024 · The pH scale was originally introduced by the Danish biochemist S.P.L. Sørenson in 1909 using the symbol p H. The letter p is derived from the German word potenz meaning power or exponent of, in this case, 10. In 1909, S.P.L. Sørenson published a … This equation is derived from the equilibrium condition for the self …
