What does BaCrO4 break into?
However, the decomposition of BaCrO4 in vacuum depends mainly upon a two-stage chemical reaction. BaCrO4 is finally decomposed into BaCr2O4 with trivalent Cr3+ cations and Ba3(Cr6+ Cr5+)2O9−x with both pentavalent Cr5+ and hexavalent Cr6+ cations after heat treatments in vacuum.
Is BaCrO4 a precipitate?
Since the Ksp for barium chromate is smaller, we know that BaCrO4 will form a precipitate first as (CrO2−4) increases so that Qsp for BaCrO4 also increases from zero to Ksp of BaCrO4, at which point, BaCrO4 precipitates.
