Solid ammonium nitrate is placed in a test-tube and solution X is added to it. The mixture formed is then warmed, and the gas released is tested using damp red litmus paper. The litmus paper changes colour from red to blue. What could be the identity of X and its role in the reaction?
- ANaOH(aq), proton donor
- BNaOH(aq), proton acceptor
- CHCl(aq), proton donor
- DHCl(aq), proton acceptor
