Answer to Question #249336 in Inorganic Chemistry for Chris

Question #249336

A is a molecule with a distorted tetrahedral structure that forms a red, volatile, and corrosive liquid at room temperature. When 465 mg of A dissolves in water, the resulting solution is acidic and requires 6.0 mmol Ba(OH)2 to neutralize it. Meanwhile, a precipitate B forms. B cannot dissolve in dilute HClO4, but the solution changes from colorless to orange, indicating that some reaction happened. After reaction, C is the major product in solution and D is the major product in the solid phase. Excessive KI is added to the orange solution C, followed by titration with thiosulfate (9.0 mmol is used). At the end point, the solution is green. A green precipitate E forms when this solution is neutralized with base. Excessive base will dissolve E to form ion F. A yellow ion G forms when F is boiled with H2O2. G turns into C when acid is added. C reacts with H2O2 under acidic conditions to form an unstable structure H. H decomposes into ion I and a gas J. Identify A – J.
