С помощью химических тестов и потенциометрии пероксид-ионы не обнаружены в BaBiO3 и KnBamBim+nOy, а также в продуктах, полученных при обработке оксидов водой, щелочью и кислотами, что с высокой вероятностью свидетельствует об отсутствии необычных валентных форм (НВФ) кислорода в виде пероксид- и супероксид-ионов в структуре исследованных оксидов. Методом потенциометрического титрования показано отсутствие в сверхпроводящих оксидах KnBamBim+nOy как НВФ кислорода, так и висмута в степени окисления &lt; +3. Найден ряд реагентов — соли Mn (II), Cr (III), Cu (II), Ce (III), основание Арнольда, метиловый красный, хромазурол S, арсеназо III, индиго- кармин и торон, позволяющих идентифицировать Bi (V) в BaBiO3 и KnBamBim+nOy. Экспериментально наблюдаемое поведение оксидов в химических реакциях по отношению к реагентам-восстановителям обусловлено наличием в их структуре Bi (V), являющегося более сильным окислителем, чем пероксидный дикислород.</p></abstract><trans-abstract xml:lang="en"><p>A radically different behavior of oxides — BaBiO3 and superconducting KnBamBim+nOy (n = 1, 2, 3; m = 1, 3, 4, 5) — and BaO2 peroxide is observed in reactions of hydrolysis and acid dissolution. Chemical tests and potentiometric analysis did not reveal peroxide-ions present in BaBiO3 and KnBamBim+nOy, as well as in the products obtained by oxide treatment with water, alkali and acids. Most probably this indicates to the absence of unusual valence states (UVS) of oxygen in the form of peroxide- and superoxide-ions in the structure of oxides under study. Data of potentiometric titration (PT) also proved the absence of oxygen UVS and bismuth in the oxidation state of &lt; + 3 in superconducting KnBamBim+nOy oxides. A number of agents (Mn (II), Cr (III), Cu (II), Ce (III) salts, Arnold’s base, methyl red, chromazurol S, arsenazo III, indigo carmine, and thoron) are revealed which provide Bi (V) detection in BaBiO3 and KnBamBim+nOy. An experimentally observed behavior of the oxides in chemical reactions regarding agents-reductants is attributed to Bi (V) present in their structure which is much stronger oxidizer compared to peroxide dioxygen.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оксид BaBiO3</kwd><kwd>валентное состояние</kwd><kwd>необычные валентные формы кислорода</kwd></kwd-group><kwd-group xml:lang="en"><kwd>BaBiO3 oxide</kwd><kwd>valence state</kwd><kwd>unusual valence states of oxygen</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках госзадания ИФТТ РАН</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Von Sholder R., Ganter K.-W., Glaser H., Merz G.
