Answer:

The
pH of the clean compound is approximately 10.495.

Explanation:

If the cleaning ion concentration of the cleaning compound is
[H^(+)] = 3.2* 10^(-11), then the
pH, no unit, of the compound is:


pH = -\log_(10) [H^(+)] (1)


pH = -\log_(10) (3.2* 10^(-11))


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


pH = -\log_(10) (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.
