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. A salt is an ionic compound formed by the reaction between an acid and a base. Salts are strong electrolytes that dissociate completely in water. This dissolution of salts in water often affects the pH of a solution.. NH 4 Cl is the salt formed in the reaction between a strong acid (HCl) and a weak base (NH 3). Only the cation, NH 2 + , will hydrolyze water. NH 4 Cl (s) + H 2 O  NH 4 + (aq) + Cl - (aq). There is a complete dissociation in water, since this is a strongly electrolytic salt.
