The interactions of carbonate anions with uranium(VI) cause the Pourbaix diagram to change greatly when the medium is changed from water to a carbonate containing solution. While the vast majority of carbonates are insoluble in water (students are often taught that all carbonates other than those of alkali metals are insoluble in water), uranium carbonates are often soluble in water. This is because a U(VI) cation is able to bind two terminal oxides and three or more carbonates to form anionic complexes.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what medium does the Pourbaix diagram change when carbonite anions interact with uranium(VI)?
Ah, so.. unanswerable

During the celebration, theaters called tablados are built in many places throughout the cities, especially in Montevideo. Traditionally formed by men and now starting to be open to women, the different Carnival groups (Murgas, Lubolos or Parodistas) perform a kind of popular opera at the tablados, singing and dancing songs that generally relate to the social and political situation. The 'Calls' groups, basically formed by drummers playing the tamboril, perform candombe rhythmic figures. Revelers wear their festival clothing. Each group has its own theme. Women wearing elegant, bright dresses are called vedettes and provide a sensual touch to parades.

Ah, so.. sensual

The King presides over a period of misrule in which conventional social rules may be broken and reckless behavior is encouraged. Festivities are held in the open air, beginning with a cercavila, a ritual procession throughout the town to call everyone to attend. Rues of masked revelers dance alongside. On Thursday Dijous Gras (Fat Thursday) is celebrated, also called 'omelette day' (el dia de la truita), coques (de llardons, butifarra d'ou, butifarra) and omelettes are eaten. The festivities end on Ash Wednesday with elaborate funeral rituals marking the death of King Carnival, who is typically burned on a pyre in what is called the burial of the sardine (enterrament de la sardina), or, in Vilanova, as l'enterro.
