Xenate disproportionation

As mentioned above, xenon trioxide is an endothermic compound which explodes violently at the slightest provocation. Aqueous solutions are stable but powerfully oxidizing. These solutions are weakly acidic ( xenic acid ) and contain molecular XeOj When these solutions are made basic. HXeO ions are formed and alkali hydrogen xenates, MHXe04, may be isolated from them. Hydrogen xenale ions disproportionate in alkaline solution to yield perxenates ...

In acid or neutral solution the xenon is present as discrete XeO molecules. In basic solutions a negative ion, HXe04, is formed. In neutral or alkaline solutions the XeO slowly decomposes to xenon and oxygen. In strong base disproportionation takes place to produce per.xenates, salts of. enon(VIII). 

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. 

Xenates contain Xe (+ VI) and they slowly disproportionate in solution to perxenates (which contain Xe (+ VIII) and Xe... 

On page 834, the statement is made Hydrogen xenate ions disproportionate in alkaline solution to yield perxenates. .. Can you confirm this assertion based on the Latimer diagrams for xenon ... 

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 ... 

The xenate anion is unstable with respect to disproportionation, yielding perxenate (XeOg" ) and elemental Xe ... 

We promised you challenging mechanisms in our introductory remarks (Section 8.1) and here is a good example. Consider reaction 8.27, which is the disproportionation of xenate...
