    Answer: The pOH value is 2.

    Explanation:

    Given: [H^{+}] = 9.9 \times 10^{-13} M

    pH is defined as the negative logarithm of hydrogen ion concentration.

    Hence, pH of the given solution is calculated as follows.

    pH = -log [H^{+}]\\= - log (9.9 \times 10^{-13})\\= 12

    The relation between pH and pOH is as follows.

    pH + pOH = 14

    Therefore, pOH is calculated as follows.

    pH + pOH = 14

    12 + pOH = 14

    pOH = 14 – 12

    = 2

    Thus, we can conclude that the pOH value is 2.
