NH3+H2SO4→NH4SO4\text{NH}_3 + \text{H}_2\text{SO}_4 \rightarrow \text{NH}_4\text{SO}_4NH3+H2SO4→NH4SO4
2NH3+H2SO4→(NH4)2SO42\text{NH}_3 + \text{H}_2\text{SO}_4 \rightarrow \text{(NH}_4\text{)}_2\text{SO}_42NH3+H2SO4→(NH4)2SO4
NH3+2H2SO4→(NH4)2SO4\text{NH}_3 + 2\text{H}_2\text{SO}_4 \rightarrow \text{(NH}_4\text{)}_2\text{SO}_4NH3+2H2SO4→(NH4)2SO4
2NH3+H2SO4→2NH4SO42\text{NH}_3 + \text{H}_2\text{SO}_4 \rightarrow 2\text{NH}_4\text{SO}_42NH3+H2SO4→2NH4SO4
