Sodium perxenate in alkaline solutions is reduced in a single step to xenon at the dropping-mercury electrode. The half-wave potential for perxenate changes from -0.21 to -0.31 volts against a Hg2SO4-Hg reference electrode in the pH range 10.1 to 11.3. Xenon (II) difluoride in acidic solution is reduced in a single step to xenon, at the potential of approximately zero against the Hg2SO4-Hg reference electrode. The reduction wave is followed by a broad maximum which can be effectively suppressed by fluoride ion. The diffusion current varies in linear fashion with concentration.
