ammonium nitrate and ammonium sulfate – can be identified by heating a solution of the ions with sodium hydroxide. This reaction produces ammonia gas, as shown in the ionic equation below: ...

Researchers developed a sustainable electrosynthesis method for NH3 from NO, achieving ampere-level current density in a pressurized electrolyzer.

It also shows that ammonia and hydrogen chloride (colourless gases) can react to form ammonium chloride again. This slideshow shows a reversible reaction involving white anhydrous copper(II ...
