    Answer is: a n aqueous solution at 25°C has a pH of 6,13.

    pOH (solution) = 7,87

    pH + pOH = 14.

    pOH (solution) = 14 - 7,87

    pOH (solution) = 6,13.

    pH is the negative of the logarithm of the H 3O⁺ ion concentration.

    pOH is the negative of the logarithm of the OH ⁻ ion concentration.
