Natriumperxenat , Na ₄ XeO ₆ is the sodium - salt of Perxenonsäure .

Extraction and presentation

The oxidation of xenon (VI) oxide XeO ₃ and sodium hydroxide solution NaOH with ozone O ₃ allows the salt to be synthesized.

${\ displaystyle {\ ce {3 XeO3 + 12 NaOH + O3 -> 3 Na4XeO6 + 6 H2O}}}$

The salt can be obtained by hydrolysis of xenon hexafluoride XeF ₆ in the sodium hydroxide solution.

${\ displaystyle {\ ce {4 XeF6 + 36 NaOH -> 3 Na4XeO6 + Xe + 24 NaF + 18 H2O}}}$

Another possibility of production would be the disproportionation of the hydrogen xenate ^- ion HXeO ₄^- in sodium hydroxide solution, whereby the yield can only be below 50%.

properties

Like most metal perxenates, the compound is stable and a strong oxidizing agent . Sodium perxenate is able to oxidize americium and manganese . The americium is oxidized from Am ³⁺ to Am ⁶⁺ and the manganese from Mn ²⁺ to Mn ⁷⁺ .

${\ displaystyle \ mathrm {8 \ Mn ^ {\, 2 +} + 5 \ Na_ {4} XeO_ {6} +2 \ H_ {2} O \ longrightarrow}}$ ${\ displaystyle \ mathrm {8 \ MnO_ {4} ^ {\, -} + 5 \ Xe + 20 \ Na ^ {\, +} + 4 \ H ^ {\, +}}}$

Xenontrioxydifluorid XeO ₃ F ₂ is the reaction product of the reaction between xenon hexafluoride XeF ₆ and Natriumperxenat.
