    Answer:

    The pH of the clean compound is approximately 10.495.

    Step-by-step explanation:

    If the cleaning ion concentration of the cleaning compound is [H^{+}] = 3.2\times 10^{-11}, then the pH, no unit, of the compound is:

    pH = -\log_{10} [H^{+}]  (1)

    pH = -\log_{10} (3.2\times 10^{-11})

    pH = -\log_{10} 3.2 - \log_{10} (10^{-11})

    pH = -\log_{10} \frac{32}{10} +11

    pH = -\log_{10} 32 + \log_{10} 10 + 11

    pH = -\log_{10} 32 +12

    pH \approx 10.495

    The pH of the clean compound is approximately 10.495.
