Answer Details
The gas that will form a white precipitate with acidified silver trioxonitrate (v) is hydrogen chloride (HCl). When HCl is reacted with silver trioxonitrate (v) in the presence of water, it produces a white precipitate of silver chloride (AgCl), which is insoluble in water and forms a white solid. The other options, NH3, SO2, and CO2, do not react with silver trioxonitrate (v) to form a white precipitate.
