An inorganic Compound `(A)` has garnet red prismatic crystals. `(A)` is modertely soluble in water and dissolved in cold concentrated `H_(2)SO_(4)` to yield red crystal `(B)` . In presence of dilute `H_(2)SO_(4)` it converts a pungent gas `(C )` into yellow turbidity `(D)` and converts a Suffocating gas `(E)` into a green solution `(F)`. the gas `(C )` and `(E)` also combine to produced the yellow turbidity `(D)` . With `KI` and starch in presence of dilute. `H_(2)SO_(4)` (A)` and concentrated `H_(2)SO_(4)` Mixture used as a cleansing agent for glassware in the laboratory . identify `(A)` and explain the reactions.
