Text Solution
Verified by ExpertsThe correct answer is:
B
Both gives yellow precipitate.
Pb 2+ + 2 I – — → Pb I 2 ↓ (yellow)
Pb 2+ + 2Br – — → PbBr 2 ↓ (white)
Ag + + Br – — → AgBr ↓ (yellow) ; AgBr + Na 3 AsO 3 — → No effect
Ag + + I – — → Ag I ↓ (yellow) ; Ag I + Na 3 AsO 3 — → No effect
No reaction is observed with Br – and I – .
