A certain metal (X) is boiled in dilute HNO3 to give a salt (Y) and an oxide of nitrogen (Z). An aqueous solution of (Y) with brine solution gives a white precipitate (P). When (Y) was treated with Na2S2O3 solution a white precipitate (Q) was obtained which on standing turns to a black compound (R).
The precipitate (Q) formed is
- Ag2S
- Ag2S2O3
- Ag2O
- Ag2SO3
Answer
(B) Ag 2 S 2 O 3
