pH Calculator
scienceConvert between pH, pOH, [H+], and [OH-], with Henderson-Hasselbalch buffer calculations.
Understanding pH & Acid-Base Equilibrium
pH is a logarithmic measure of the hydrogen ion concentration in an aqueous solution. Proposed by Søren P. L. Sørensen in 1909, pure water at 25°C has [H⁺] = 1.0 × 10⁻⁷ M, yielding a neutral pH of 7.0.
