The pOH of a solution is calculated using the formula pOH = -log[OH-]. However, since HI is a strong acid, it dissociates completely in water to produce H+ ions, not OH- ions. The concentration of H+ ions would be 1.0×10^-4 M. The pH of the solution can be calculated as pH = -log[H+] = 4. Since pH + pOH = 14 for aqueous solutions at 25°C, the pOH = 14 - pH = 14 - 4 = 10.00.
