Ferric Chloride and Ferric Nitrate are inorganic salts Noel and are very strong oxidizing agents. Fe(NO3)3(aq) + 3 KI(aq) --> FeI3(aq) + 3 KNO3(aq) Unfortunately, no reaction will occur in this case. The soluble salts form lightly tinted (ferric sulfate) or colorless (potassium thiocyanate) solutions. While there is no difference between the chloride, sulfate and nitrate salts of potassium insofar as the potassium ion is concerned, there may be a difference on plant response due to the associated ion. Horn MS, Circeo RB, Hassan C. Radiographic artifacts produced by silver nitrate and Monsel’s solution (letter). The potassium, iodine, lead and nitrate ions dissolve, and the potassium ions react with the nitrate ions to form potassium nitrate while the lead ions react with the iodine ions to form lead iodide. 2. Lead nitrate and potassium iodide, which are the reactants, are powders that react to form a yellow-colored lead iodide and a colorless potassium nitrate. In this experiment the following reactions will be considered and observed. Add a few drops of potassium thiocyanate solution and observe the reaction. So we identify ferric thiocyanate as the precipitate. Ferric nitrate (nitrate of iron) is generally made by dissolving scrap iron in nitric acid of 1.30 sp. Prepare separate solutions of soluble potassium thiocyanate and ferric sulfate salts. Add the each solution from the flask to the solution in the beaker and observe, the color change. 2.
