Sulfuric Acid and Ammonia (Ammonium Sulfate)
H2SO4 + 2NH3 → (NH4)2SO4
Visão geral
Sulfuric acid reacts with ammonia to form ammonium sulfate, a major nitrogen-sulfur fertilizer containing 21% nitrogen and 24% sulfur. The reaction is strongly exothermic and proceeds readily. Ammonium sulfate was historically a major byproduct of coke oven operations.
