Which of the following will be precipitated when dil. HCl is added to their solution.

A balck coloured compound (A) on reaction with dilute H_(2)SO_(4) gives a gas (B) which on passing in a solution of an acid (C ) gives a white turbidity (D). Gas (B ) when passed in an acidified solution of a compound (E ) gives a precipitate (F) soluble in dil HNO_(4) . After boiling this solution when an excess of NH_(4)OH is added, a blue coloured compound (G) is formed. To this solution on addition of acetic acid and aqueous K_(4)[Fe(CN)_(6)] a chocolate precipitate (H) is obtained. On addition of an aqueous solution of BaCl_(2) to an aqueous solution of (E) , a white precipitate insolution in HNO_(3) is obtained. Identify (A) to (H).

How many of the following are correct. (i) A white precipitate is obtained when a solution of BaCl_(2) is treated with Na_(2)SO_(3) (ii) A white precipitate is obtained when a solution of NaAlO_(2) is heated with NH_(4)Cl (iii) A white precipitate is obtained when H_(2)SO_(4) is passed through a solution of ZnSO_(4) (iv) A white precipitate is obtained when a solution of ZnSO_(4) is treated with one of Na_(2)CO_(3)
