No AgCl is not soluble, the reasoning of it being soluble because NaCl is, is incorrect. NaCl is soluble because it is a group 1 metal. AgCl is no because it forms a precipitate.
Group 1: Insoluble Chlorides. Most metal chloride salts are soluble in water; only Ag, Pb, and Hg 2 form chlorides that precipitate from water. Thus the first step in a qualitative analysis is to add about 6 M HCl, thereby causing AgCl, PbCl 2, and/or Hg 2 Cl 2 to precipitate.roup 2: Acid-Insoluble Sulfides. Next, the acidic solution is saturated with H 2 S gas. Only those metal ions that form very insoluble sulfides, such as As, Bi, Cd, Cu, Hg, Sb, and Sn, precipitate as their sulfide salts under these acidic conditions.
