Oxidation-Reduction Redox Flag Demonstration Kit

The Oxidation-Reduction Flag Kit from Innovating Science provides a visual demonstration of redox (reduction-oxidation) reactions. Students paint potassium thiocyanate and potassium ferrocyanide solutions onto filter paper, allow it to dry, and then spray with iron(III) chloride to observe blue and red color changes. The demonstration also provides insight into testing for iron(II) and iron(III) ions in solution. The kit includes a spray bottle, iron(III) chloride solution, potassium thiocyanate solution, potassium ferrocyanide solution, instructions, and a safety data sheet. For laboratory use only.
