Perxenate ion

Salts containing the octahedral Xe(VIII) perxenate ion Xe04-g are known, and by the action of acid the tetrahedral xenon teroxide Xe04 is formed. [Pg.184]

In acid solution 03 is exceeded in oxidizing power only by fluorine, the perxenate ion, atomic oxygen, OH radicals, and a few other such species. The rate of decomposition of ozone drops sharply in alkaline solutions, the half-life being 2 min in 1 M NaOH at 25°C, 40 min at 5 M, and 83 h at 20 M ... [Pg.455]

The HXe04 ion subsequently disproportionates to form the perxenate ion, XeOe ... [Pg.295]

The perxenate ion is an even more powerful oxidizing agent than Xe03 and is capable of oxidizing Mn to permanganate, Mn04 in acidic solution. [Pg.295]

Write a balanced equation for the oxidation of Mn to Mn04 by the perxenate ion in acidic solution (assume that neutral Xe is formed). [Pg.298]

The trioxide is the anhydride ofxenic acid, H2Xe04. In aqueous basic solution, the acid forms the hydrogen xenate ion, HXe04", which further disproportionates to the perxenate ion, XeOe, in which xenon attains its highest oxidation number of +8. [Pg.201]

Starting from xenon and fluorine and other appropriate reagents, is prepared potassium perxenate. Using VSEPR theory, the probable structure of perxenate ion, predicted ... [Pg.199]

For the structure of perxenate ion please refer to page number 27. [Pg.200]

The addition of alkali to Xe03 solutions yields xenate ions [HXeOJ. Although salts of this species can be isolated, solutions containing [HXe04] disproportionate to give the perxenate ion, [Xe06]4", and xenon ... [Pg.65]

Aqueous [Xe05] is formed when O3 is passed through a dilute solution of XeOs in alkali. Insoluble salts such as Na4Xe0g-8H20 and Ba2XeOg may be precipitated, but perxenic acid H4Xe06 (a weak acid in aqueous solution) has not been isolated. The perxenate ion is a powerful oxidant and is rapidly reduced in aqueous acid (equation 18.13). Oxidations such as Mn(ll) to [Mn04] occur instantly in acidic media at 298 K. [Pg.569]

Draw a Lewis structure for and a VSEPR diagram showing the molecular geometry of the perxenate ion, XeOg . [Pg.586]

If Xe03 is dissolved in strong alkali, it slowly disproportionates to xenon and the perxenate ion, Xe06 (aq) ... [Pg.92]
