Salt solution to seawater samples, extraction solution for soil samples, etc. Thiocyanate can form complexes with ferric and ferrous ions. Common derivatives include the colourless salts potassium thiocyanate and sodium thiocyanate. Instead of using a prepared reagent which gradually deteriorates, the ferrous salt and thiocyanate are added in aqueous solution during the test, and, moreover, ferrous salts appear to be more stable in this solvent than in acetone.
