Answer:
A precipitate formed. The one that does not react is the salt from fluoride because it is soluble
Step-by-step explanation:
The halide salts are made of:
Cl⁻ → Chloride
F⁻ →Fluoride
Br⁻ → Bromide
I⁻ → Iodide
The solution contains AgNO₃
When the AgNO₃ dissociates in aqueous solution, it produces silver cation and nitrate anion
AgNO₃ (aq) → Ag⁺ (aq) + NO₃⁻(aq)
Ag⁺ can react to the halides and the all make precipitate except for the F⁻
Ag⁺(aq) + Cl⁻(aq) → AgCl (s) ↓
Ag⁺(aq) + F⁻(aq) →AgF (aq)
Ag⁺(aq) + Br⁻(aq) → AgBr (s) ↓
Ag⁺(aq) + I⁻ (aq) → AgI (s) ↓
