Q1. In the following reaction, identify the salt formed: NH4OH (aq) + H2SO4 (aq) -> .......... + 2H2O (l)

A (NH4)2S

B (NH4)3SO4

C NH4NO3

D (NH4)2SO4 Correct

Explanation

Ammonium hydroxide is a base and sulphuric acid is an acid, so the reaction is a neutralisation reaction. Sulphuric acid supplies the sulphate ion, and two ammonium ions are needed to balance its charge, giving ammonium sulphate, (NH4)2SO4, along with water. Ammonium sulphide, (NH4)2S, would require sulphide, not sulphate. (NH4)3SO4 has an incorrect ion ratio and is not the normal neutral salt here. Ammonium nitrate, NH4NO3, would be formed from nitric acid, not sulphuric acid.
