Actually most of the salts are insoluble in water. Not all the salts include chloride!!! And of those witch contain chloride, silver, led and mercury salts are insoluble!!! chemically speaking, not all salts are soluble in a particular solvent under normal conditions..
Salts containing the ammonium ion (NH4+) are also soluble. 2. Salts containing nitrate ion (NO3-) are generally soluble. NO3^- All nitrates are soluble. 3. Salts containing Cl-, Br-, I-are generally soluble.Important exceptions to this rule are halide salts of Ag+, Pb2+, and (Hg2)2+.Thus, AgCl, PbBr2, and Hg2Cl2 are all insoluble.Cl-All chlorides are soluble except AgCl, Hg2Cl2, and PbCl2..
