    Answer:

    2.22×10⁻⁹ M

    Explanation:

    Applying,

    [OH⁻][H⁺] = 1×10⁻¹⁴………………. Equation 1

    Where [OH⁻] = Hydroxyl ion concentration, [H⁺] = Hydrogen ion concentration.

    make [OH⁻] the subject of the equation,

    [OH⁻] =  1×10⁻¹⁴/[H⁺]…………… Equation 2

    From the question,

    Given: [H⁺] = 4.51×10⁻⁶ M

    Substitute into equation 2

    [OH⁻] = 1×10⁻¹⁴/4.51×10⁻⁶

    [OH⁻] = 2.22×10⁻⁹ M
