Hydrobromic acid is a strong acid, so it dissociates completely in water. The concentration of H+ ions will be the same as the concentration of the acid, 0.025M. The pH is calculated using the formula pH = -log[H+], which gives pH = -log(0.025) = 1.60. The pOH can be found using the relation pOH = 14 - pH, which gives pOH = 14 - 1.60 = 12.40.
