In the specific chemical detection of halogens via silver nitrate testing on an acidified Lassaigne' — Qualitative and Quantitative Analysis Chemistry Question

💡 Solution & Explanation

Addition of $AgNO_3$ to halide ions yields specific precipitates: $AgCl$ is a white precipitate soluble in $NH_4OH$ (forming a diamminesilver complex). $AgBr$ is a pale yellow precipitate only sparingly soluble in $NH_4OH$. $AgI$ is a yellow precipitate that is completely insoluble in $NH_4OH$.
