Answer 1

here I'm taking chloride salt of silver *****Although Ag⁺, Pb²⁺, and Hg₂²⁺ all form insoluble white chlorides, Ag⁺ is the only one of these cations that forms an ammonia complex. Therefore, AgCl dissolves readily in aqueous NH₃. When the resulting solution is acidified with HNO₃, AgCl reprecipitates. [[EQUATION***** 1. AgCl(s) + 2NH₃(aq) → Ag(NH₃)²⁺(aq) + Cl^-(aq)
2. Ag(NH₃)²⁺(aq) + Cl^-(aq) + 2H₃O⁺ → AgCl(s) + 2NH₄⁺ + 2H₂O]

Add 3 M HCl dropwise to the solution being tested. If a white precipitate is formed, centrifuge and remove the supernatant liquid. Add 6 M NH₃ solution to the precipitate. If the precipitate dissolves, add 10 M HNO₃. [****OBSERVATION Formation of a white precipitate ] [**** CONCLUSION-- Ag⁺.PRESENT IN A GIVEN SALT] THANK YOU VERY MUCH
