Its capability as a flame retardant can be uplifted by mixing it with ammonium sulfate. As a flame retardant, it builds ignition temperature of the material, diminishes the most significant weight reduction rate, and leads to expansion for the buildup or burn. Ammonium sulfate is used as a flame retardant acting. How is ammonium sulfate used as a flame retardant? (3 marks)Īns. In this way, we get a molecule of ammonium sulfate. In (NH 4) 2SO 4, 2 molecules of NH 4( ) donate 1-1 electrons to SO 4(2-) to complete the octet of Sulphate ions, forming an ionic bond between the two. What will be the structure of (NH 4) 2SO 4? (2 marks)Īns. But its use as a wood preservative was discontinued because it is hygroscopic and led to problems like metal clasp corrosion, uneven finish, and unsteady dimensions. Earlier, Ammonium sulfate was used as a wood preservative being hygroscopic. Why is Ammonium sulfate no more used as a wood preservative? (2 marks)Īns. Ammonium sulfate is an inorganic salt with high solubility in water but is insoluble in alcohol, acetone, and ether.Ammonium sulfate is used as a food additive to "salt out" proteins via precipitation, examining rubber grids, treating drinking water, flame retardant, acidity controller, pH controller, etc.It can be formed by treating ammonia with sulphuric acid or reacting finely added gypsum to an ammonium carbonate solution. It is composed of NH4( ) cation and SO4(-2) anion. Ammonium sulfate is an odourless, whitish solid crystallized compound.Ammonium sulfate is even recorded as an essential ingredient for vaccines in the United States as per the Centre for Disease Control.Ammonium sulfate is utilized to treat drinking water after blending with chlorine producing monochloramine as a result of the disinfection.Ammonium sulfate also works as a pH controller for various cultures and solutions.It has its application as a cleaning additive and as a flame retardant as well.It is used for the purpose of precipitation of various ammonium salts and ammonium persulfate. Ammonium sulfate is highly dissolvable in water because of its ionic nature, and as a result, it " salt out" the precipitated protein. The dissolvability of the proteins is directly proportional to the quality of expansion in the ionic solution of ammonium sulfate.
