One is treated with excess iron (III), and the other with excess thiocyanate. I need the *accepted* value. Answer Save. Peroxide Test Strips Strips are available from laboratory supply companies. C2FeN2S2. Ammonium thiocyanate solution. Preparation. A suspension of 1-aminoanthraquinone (3.0 g) in 45 ml of DMSO was treated with ammonium thiocyanate (9 g), then heated to 50°C, and 15 ml H 2 SO 4 added dropwise. potassium thiocyanate is a compound formed with one K+ cation and one SCN- anion. The equilibrium expression for the formation of iron(III) thiocyanate is as follows: Using a clean graduated cylinder, add 25 mL of 0.0020 M KSCN to a 100 mL beaker.
