Silver sulpho-carbonate is prepared from silver carbonate and sulpho-carbolic acid. It occurs in the form of white, prismatic needles, containing twenty-eight per cent. of silver. It must be protected from light and air to prevent it from splitting up into metallic silver and phenol.
It is said to possess valuable antiseptic properties, and to be preferable to nitrate of silver for such purposes as the latter agent is employed, on account of its non-corrosive action. Dr. Harlan speaks of it acting very well in deep pyorrhoea pockets. It is soluble in water in three to ten per cent. solutions.
