Question
Aqueous hypo solution on reaction with aqueous AgNO3 gives :
Options
A.yellow precipitate changing to black
B.white precipitate changing to black
C.orange precipitate to blue
D.orange precipitate to blue
Solution
S2O32- + 2Ag+ → Ag2S2O3↓ (white) ; Ag2S2O3 + H2O → Ag2S↓ (black) + H2SO4
This hydrolytic decomposition can be accelerated by warming.
If hypo is in excess, then soluble complex is formed.
2S2O32- + Ag+ → [Ag(S2O3)2]3- (soluble complex) or [Ag(S2O3)3]5-
