OK, that was very short answer, now a little bit longer one. This is case of strong acid titrated with strong base, so we expect pH at equivalence point to be that of neutral solution - that is, 7.00. The smaller the the pKa, the larger the Ka meaning the acid is strongly dissociated into H3O+. So indeed HClO is a strong acid compare to HBrO (pKa = 8.69). In order to determine the pH of a HClO solution, you need to know the concentration of H3O+ in that solution because pH = -log[H3O+].
