The acid ionization constants of the products were determined, their electron absorption spectra were measured, and schemes of acid-base equilibria in aqueous solution were proposed Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Skorik, Yu.A.; Neudachina, L.K.; Osintsev, A.
