Iron thiocyanate solubility
WebMay 11, 2015 · In the presence of oxygen the sodium sulphide is oxidized to thiocyanate: Na2S + NaCN + H2O + 1/2 O2 = NaCNS + 2 NaOH. Sodium ferrocyanide ionizes thus: Na4Fe (CN)6 <–> 4Na+ + Fe (CN)6==. The iron … WebChemical Properties of Potassium Thiocyanate – KSCN Potassium thiocyanate reacts with iron (III) nitrate forms iron (III) thiocyanate, nitric acid and potassium oxide. 3H2O + 2Fe (NO3)3 + 6KSCN → 2Fe (SCN)3 + …

The common-ion effect can be applied to a solution of lead thiocyanate when potassium thiocyanate is added. Since there is a common ion, the cyanate ion, the molar solubility of lead thiocyanate goes down in the presence of potassium thiocyanate.
