When mercurous nitrate paper is exposed to ammonia gas then black color is produced due to the formation of Hg₂NH₂NO₃ + Hg.
The reaction of mercurous nitrate paper with ammonia gas produces the compound mercury amidonitrate and mercury metal.
This mercury amidonitrate contains the mercury I ion (Hg2^+). Since the compound contains mercury I ion, mercury amidonitrate has the formula; Hg₂NH₂NO₃.
The compounds formed therefore are; Hg₂NH₂NO₃ + Hg
