Yields of hydrogen ions have been measured by pulse radiolysis with optical registration of short-lived species and by use of chromate ions and pH indicators as scavengers of H 3 0 + . It was found that G(H,O+) for the bulk of the solution (after the completion of reactions in spurs) is -3-3.3 ions/100 eV. Some reactions of H30+ ions were also studied by the pulse radiolysis method. The rate constants of their reactions with pH indicators-bromophenol blue, phenol red and bromothymol blue-were determined. They are 1.6 x lo'', 7.2 x 1O1O and 8.8 x 10" dm3 mol-' s-l respectively.The earlier conclusion that free hydrogen ions take no part in the formation of C1during pulse radiolysis of neutral aqueous solution of alkaline metal chlorides was confirmed on the basis of results of the investigation of the influence of CrO2additions and temperature on G(C1t).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
