✦ Synopsis

The dissolution rate of liquid gallium anodes in 1 N solutions of hydrochloric acid, sulphuric acid and sodium hydroxide at 3O+'C has been measured radiochemically under galvanostatic conditions (O-12 mA/cm2). In the hydrochloric acid solution, the anodes consume very nearly 2 F/g-atom gallium di&ol&d. In the iwo other solutions, the corresponding number is higher bd approaches 3 with increasing current. It is concluded that lower-valent gallium species are formed (at least as intermediates) in all three solutions. R&umb-Etude radiochimique sous conditions galvanostatiques (12 mA/cme) de la vitesse-de dissolution d'anodes de Ga liq. dans des solutions normales HCl, HBS04 ou NaOH & 30,Y'C. Aver HCl, la consommation &ctrique est environ 2 F/at. g. Ga dissous. Avec les deux autres solutions, elle est plus Bev& et tend vers 3 quand le courant augmente. L'on en dkduit, qu'au moins comme intermediaires, des &ats sous-valents du Ga sont engendres dans tous les cas. Zusammenfassung-Die Aufl6sungsgeschwindigkeit fltissiger Galliumanoden in 1 N LBsungen von HCl, HISOl und NaOH wurde bei 30,YC. radiochemisch unter galvanostatischen Bedingungen (O-12 mA/cm*) gemessen. In salzsaurer LGsung werden beinahe 2 F pro g-Atom aufgel&tes Gallium verbraucht. In den beiden andem Lijsungen .ist die entsprechende
