Question
When aqueous $AgNO_3$ is added to halide extracts, specific precipitates form. Which of these silver halide precipitates dissolves completely and readily in a dilute, aqueous ammonia solution due to complex formation?
Answer: C
💡 Solution & Explanation
Silver chloride ($AgCl$) is a white precipitate that dissolves easily in dilute $NH_4OH$ to form the soluble diamminesilver(I) complex, $[Ag(NH_3)_2]^+$. $AgBr$ is only sparingly soluble, and $AgI$ is entirely insoluble in ammonia.
