The chemical states of oxygen on the surfaces of Pr_{1-x}Sr_{x}CoO_{3} (x=0.5 and 0.7) oxide systems were investigated by X-ray photoelectron spectroscopy. Merged oxygen peaks of Pr_{1-x}Sr_{x}CoO_{3} (x=0.5 and 0.7) oxides could be divided as five sub-peaks. These five sub-peaks could be defined as lattice oxygen (O_{L}). chemisorbed oxygen peaks (O_{C}) and hydroxyl condition oxygen peak (O_{H}). In case of the Pr_{0.5}Sr_{0.5}CoO_{3} and Pr_{0.3}Sr_{0.7}CoO_{3}, the binding energy (BE) of oxygen lattice were located at same BE. However, the BE of chemisorbed oxygen peaks including oxygen vacancy shows different BE. Especially, it was found that BE of chemisorbed oxygen peaks was increased when more Sr were substituted. Comparing atomic percentages of oxygens of Pr_{0.5}Sr_{0.5}CoO_{3} and Pr_{0.3}Sr_{0.7}CoO_{3}, the ratio of Pr_{0.3}Sr_{0.7}CoO_{3} was higher than that of Pr_{0.5}Sr_{0.5}CoO_{3}. It showed more chemically adsorbed site including oxygen vacancies were existed in Pr_{0.3}Sr_{0.7}CoO_{3}.
