Nov 10, 2009· In extending these studies to ammonium sulfate solutions, we report the value of γ e as defined by Eq. 2.Here, however, p sat is the equilibrium vapor pressure of the solution, rather than that of pure water. Because this vapor pressure is ≈13% lower than that of pure water, the maximum theoretical evaporation rate for the solution is lower than that of pure water.

Uses. The primary use of ammonium sulfate is as a fertilizer for alkaline soils.In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of ammonium sulfate is its low nitrogen content relative to ammonium nitrate, which elevates transportation costs.
