What is ammonium chloride?
Flexi Says:
Ammonium chloride (NH4Cl) is a salt that is formed when the strong acid HCl is neutralized by the weak base NH3. Ammonium chloride is soluble in water. The chloride ion produced is incapable of hydrolyzing because it is the conjugate base of the strong acid HCl. In other words, the Cl− ion cannot accept a proton from water to form HCl and OH−, as the fluoride ion did in the previous section. However, the ammonium ion is capable of reacting slightly with water, donating a proton and so acting as an acid.
