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.
The purpose of this experiment is to measure the volume and mass of a sample of butane, and to use these values to determine the molar mass.

On Wednesday the 9th of March at 07:38am Regents International School students were lucky enough to view one of the rarest celestial events, an eclipse of the Sun.
The Sun was partially eclipsed for nearly 2 hours and at its maximum coverage, 41% was hidden from our view by the Moon.
Many students took part and viewed the event through pin hole cameras, the camera on their mobile device and most successfully by looking through a CD. All of these methods made it safe see what was happening and gave us all an unforgettable experience.
