As part of their Chemistry A-level, sixth formers are required to perform several practical experiments over the two years.
This afternoon, the Lower 6th students determined if the mass of iron present in an Iron (II) sulfate tablet is as the bottle specifies. They achieved this by performing a redox titration with potassium manganate and a solution of Iron (II) ions made up as a standard solution.
It was a pleasure to see them working so carefully and with great attention to safety. Well done, Lower 6th!
