Excerpt from The Dublin Journal, Vol. 5: Of Medical and Chemical Science; Exhibiting a Comprehensive View of the Latest Discoveries in Medicine, Surgery, Chemistry, and the Collateral Sciences
I fortunately possessed in the laboratory book such accounts of the experiments as may be sufficient for that purpose.
A solution of the chloro-stannite of ammonium (first described by my friend Dr. Apjohn) was placed to evaporate in an unglazed biscuit ware capsule, in which there had been many weeks before chloride of platinum. The tin solution gradually became coloured red, and seeking for the cause of this, it appeared that the trace of platinum, which the dish had absorbed, was sufficient to colour intensely the solution of the chloro-stannite. To verify this rationale I mixed together solutions of proto-chloride of tin and per-chloride of platinum. A splendid red colour was immediately produced. To determine the nature of the body formed by the union of the two chlorides, and which possesses this brilliant tint, was the object of my future investigations.
Per-chloride of platinum and crystallized proto-chloride of tin were dissolved separately in small portions of water, and the solutions mixed: they became instantly of an intense wine red colour. This red liquor was divided into two equal portions; one portion was evaporated very cautiously nearly to dryness, when on cooling it solidified into a mass of intensely deep red crystals, very deliquescent, and staining the skin brown. They were soluble in a small quantity of water, in alcohol and in ether; these solutions were red. When they were evaporated the substance again separated in the crystalline form. It crystallized more readily from its etherial than from its alcoholic or watery solution.
These crystals are in plates, presenting an appearance like moiree metallique.
