On the evaporation of ammonium sulfate solution

Nov 10, 2009Molecular dynamics (MD) simulations of ammonium sulfate solution in the interfacial region show the sulfate anion completely depleted from the interface to a depth of ≈7 Å . This result is in agreement with interpretations of surface tension measurements of ammonium sulfate solution ( 27 ).

Ammonium Sulfate

In general, the industrialized regions account for most of the world's ammonium sulfate capacity, with Western Europe and the United States being overtaken by China in recent years. Because much of ammonium sulfate is produced involuntarily as a by+product or coproduct, the volume of production is influenced more by general industrial output

Ammonium sulfate

As a salt of a strong acid (H2SO4) and weak base (NH3), its solution is acidic; pH of 0.1 M solution is 5.5. In aqueous solution the reactions are those of NH4+ and SO4−2 ions. For example, addition of barium chloride, precipitates out barium sulfate. The filtrate on evaporation yields ammonium chloride.

Ammonium chloride: The % dissociation of weak ammonium hydroxide (base) decreases in an ammonium chloride solution. Ammonium chloride dissociates to release ammonium ions and shifts the equilibrium left. Hydrolysis: When salts of weak acids or bases dissolve in water, one of the ions undergoes hydrolysis to reform the weak acid or base.
