Solution

Correct Answer:

AgNO3

The Test: Add Silver Nitrate ( $A g N O_{3}$ ) to the acidified salt solution.
Observation: A white curdy precipitate of Silver Chloride ( $A g Cl$ ) is formed.
Equation: $C l^{-} + A g^{+} \to A g Cl ↓$ .
Chemical Properties: The precipitate is insoluble in concentrated nitric acid but soluble in Ammonia solution (forming the complex $[A g (N H_{3})_{2}] Cl$ ).
Light Sensitivity: $A g Cl$ turns greyish-purple on exposure to sunlight due to decomposition into metallic silver.
