Quantitative Chemistry – calculating the percentage composition of iron in iron tablets.
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.

TED Periodic Table Videos
TED Periodic table videos A fantastic resource by the University of Nottingham where they have produced a video on all 118 elements. Each video (where possible) shows the elements in their natural state and their common reactions. They have also produced a QR code version of the periodic table so that students can interact and … Continue reading TED Periodic Table Videos
