The pOH is calculated using the formula pOH = 14 - pH. For a strong acid like HCl, the concentration of H+ is approximately equal to the concentration of the acid, so [H+] = 0.010 M. The pH is calculated as -log(0.010) = 2.00. Therefore, pOH = 14 - 2.00 = 12.00. However, considering the activity coefficients, the effective concentration of H+ is 0.010 * 0.83 = 0.0083 M, so pH = -log(0.0083) ≈ 2.08, and pOH = 14 - 2.08 = 11.92.
