Ammonium Chloride is a soluble salt prepared by :
b) Neutralisation
Ammonium chloride is an inorganic compound with the formula NH4Cl and a white crystalline salt that is highly soluble. When ammonium hydroxide is made to react with hydrochloric acid, eventually crystals of ammonium chloride separate out. Heating to evaporate the water and then cooling is found to be more effective.
