Step-by-step laboratory practicals for IB, IGCSE & GCSE Science
Iron tablet titration is a common laboratory method used to determine the amount of iron present in a sample, such as an iron supplement tablet. This method involves reacting the iron in the tablet with a solution of potassium permanganate (KMnO4) to produce a purple colour. The endpoint of the titration is reached when the purple colour disappears, indicating that all of the iron in the tablet has reacted with the KMnO4.
