Reddish brown (chocolate) precipitate is formed by mixing solutions containing:

A scalet compound A is treated with concenbtrated HNO_(3) to gave a chocolate brown precipitate B. The precipitate is filtered and the filtrate is neurralised with NaOH Addition of KI to the resulting solution gives a yellow precipitate C the brown precipitate B on warming with concentrated HNO_(3) in the presence of Mn(NO_(3))_(2) produces a pink coloured solution due to the formation of D identify A, B,C, and D write the reaction sequence.

lodine crystals are added to liquor ammonia and the brown precipitate so formed is separated , dried and spread on floor. On walking over the precipitate harmless explosion occurs releasing coloured gas. The ppt. and coloured gas are respectively
