    Which of the following relationship is correct?
    Question

    Which of the following relationship is correct?

    A.

    Cₕ⁺ + Cₒₕ⁻ = 14

    B.

    Cₕ⁺ × Cₒₕ⁻ = 14

    C.

    pH + pOH = 14

    D.

    pH × pOH = 14

    Correct option is C


    The correct relationship in aqueous solutions at 25°C is:
    pH + pOH = 14
    This equation derives from the ionic product of water (Kw = 10⁻¹⁴). It helps determine the acidity or basicity of a solution.
