WebApr 12, 2024 · Gladstone's report is pointing to the product as the neutral species iron (III) thiocyanate, Fe (SCN) 3, formed in what is often (and unhelpfully, IMO) termed a double displacement reaction. Following Gladstone's work, the consensus appears to have been that the colour was due to Fe (SCN) 3 or Fe (CNS) 3, and this prevailed into the 20th century.
