A certain metal (A) is boiled in dilute nitric acid to give a salt (B) and an oxide of nitrogen (C). An aqueous solution of (B) with brine gives a precipitate (D) which is soluble in ammonium hydroxide. On adding aqueous solution of (B) to hypo solution, a white precipitate (E) is obtained. (E) on standing turns to a black compound.Compound (A) to (F) are identified as:
(A) : Ag; (B) : AgNO3, (C) : NO2 , (D) : AgCl, (E) : Ag2S2O3 and (F) : Ag2S
If true enter 1, else enter 0.
