    PH scale is used to determine how acidic or basic a solution is.

    we have been given the hydrogen ion concentration. Using this we can calculate pH,

    pH = - log[H⁺]

    pH = - log (1 x 10⁻¹ M)

    pH = 1

    using pH can calculate pOH

    pH + pOH = 14

    pOH = 14 - 1

    pOH = 13

    using pOH we can calculate the hydroxide ion concentration

    pOH = - log [OH⁻]

    [OH⁻] = antilog (-pOH)

    [OH⁻] = 10⁻¹³ M

    hydroxide ion concentration is 10⁻¹³ M
