Name According to the Monograph in FP II	Polish Name	Synonyms FP II	Description (Original Wording)	Form and Properties (Original Wording)
Argentum colloidale	Srebro koloidalne	Corgol, Collargol	Argentum colloidale should contain not less than 70% Ag (atomic weight 107.9), the rest is: protein or gelatin and a small amount of silver chloride	Dark gray flakes with a metallic sheen, odorless, with a faint metallic taste. Colloidal silver slowly dissolves in the water. Argentum colloidale solution in 50 parts of water is opaque, and in reflected light—cloudy; becomes transparent when diluted with plenty of water, in reflected light, however, it is still cloudy.
Argentum gelatinosum	Żelatynian srebrowy	Argentum gelatosatum, Gelargin, Albargin, Gelatynian srebrowy	Argentum gelatinosum should contain no less than 14.6% and no more than 15% Ag (atomic weight 107.9)	Yellowish, fine, shimmering, odorless powder with a salty-insipid taste. Argentum gelatinosum is easily solublein water giving neutral or slightly acidic solutions.
Argentum nitricum	Azotan srebrowy	Argenti nitras, Argentum nitricum crystallisatum, Lapis infernalis, Lapis, Kamień piekielny	The preparation should contain no less than 99.6% AgNO3	Colourless, odourless, transparent belts of the rhombic system. Silver nitrate dissolves in 0.5 part of water, in 15 parts of alcohol; very sparingly soluble in ether and glycerol. M.p. around 208 °C. Silver nitrate at 208 °C has the form of a yellowish liquid, which after solidification forms a white, crystalline mass; heated at a temperature higher than 208 °C, it gradually decomposes, releasing brown fumes.
Argentum nitricum cum Kalio nitrico	Azotan srebrowy z azotanem potasowym	Argenti nitras et Kalii nitras, Argentum nitricum fusum mitigatum, Lapis infernalis mitigatus	Silver nitrate with potassium nitrate should contain no less than 32.3% and no more than 33.5% AgNO3 (MW 169.9); the rest is potassium nitrate.	White or greyish-white, odourless, hard sticks with a smooth fracture, very soluble in water.
Argentum nitricum fusum	Topiony azotan srebrowy	Argenti nitras fusus	Fused silver nitrate should contain no less than 94.5% and no more than 95.5% AgNO3 (MW 169.9); the rest is potassium nitrate.	White or greyish, odorless sticks with a crystalline break. Fused silver nitrate dissolves very easily in water.
Argentum proteinicum	Proteinian srebrowy	Argentum proteinatum, Prorgol, Protargol	Silver proteinate should contain no less than 8% and no more than 8.4% Ag (atomic weight 107.91).	Yellow-brown, shiny flakes or yellow-brown, fine powder, almost odorless, with a first bland, then metallic taste. Silver proteinate is easily soluble in water, giving solutions of weakly alkaline reaction.
